  • The reason for not discussing that is that generally, you shouldn't mix exported functions and methods. That's because a method really expects to be called with an object as its first argument, which is less likely to happen correctly if you say method($obj) instead of $obj->method(). Also, you don't get inheritance because you're not going through method dispatch.

    I'm sure there are a few cases where you might want to export things, but generally, I'd think twice before pulling in Exporter.

    • I was just about to say that, but you beat me to it :)
    • You lost me. I understand the $obj->method thing, but what I didn't understand and had hoped Dave would get into was the whole Exporter thing. What is it, why is it used, etc...

      Some objects are written such that when you use them, you have to import the methods you'll be using, like:

      use My::Module qw/ method1 method2 /;
      And others are written so you can just say:

      use My::Module;
      And then you automatically have access to the methods.

      • I think you're getting confused between ordinary functions and OO code (methods). If you don't call it with an arrow, it's not a method, it's a function (with the annoying exception of the indirect method call syntax, but don't worry about that yet).

        When you use a module, you're actually using OO behind the scenes, even though the results aren't usually OO. What happens is that Perl ends up calling the import() method of the named class and passing it the list that you have supplied.

  • Eating healthily in the UK and even london is fairly easy if you stick to a balanced diet rather than american health fads.

    Drink fresh fruit juice instead of fizzy drinks, avoid places like macdonalds and instead go to places like Beetroot in soho or any Felafel restaurant. Even the average pub grub in london is fairly well balanced, just so long as you have carbs in the day and protein in the evening. The hotel you stayed in would have provided continental breakfast so thats the day sorted.

    • That said, I still find even the snack food far superior in european countries that aren't the UK. Whilst you can eat healthy in the UK, it's still harder than it should be.

    • Not excusing my tubby compadres in America, but I wouldn't be too smug:

      (Source [eufic.org]) The most comprehensive data on the prevalence of obesity worldwide are those of the World Health Organisation MONICA project (MONItoring of trends and determinants in CArdiovascular diseases study) [14]. Together with information from national surveys, the data show that the prevalence of obesity in most European countries has increased by about 10-40% in the past 10 years, ranging from 10-20% in men and 10-25% in women [15].

      • Too true.

        And in whose footsteps did we follow this trend..? The home of fast food, the United States.

        Fortunately the government acknowledges the problem and is doing something (although, as always, just a token effort rather than really making a difference).

        It isn't hard to eat healthily though, most of the obesity isn't because there isn't access of healthy food (very very few people, and certainly a tiny minority of the overweight are more than a mile from the nearest affordable source of fresh vege

        • No excuses, only laziness.

          Unhappily so.

          Supermarkets aren't quite so prevalent here (at least in Pittsburgh) because they tend to be larger and most people drive instead of walk for their groceries. (Boo!) But it's actually much easier to eat healthier almost everywhere you go now -- even many fast food places have one or two items that, while you might not want it for every meal, will do in a pinch. (Salads and such.) I don't think it's a coincidence that it's also much easier to get at least decent bee

          • Heh. McDonalds "Salads Plus" is what we have over here. I do wonder how many calories are in the dressing though.

            It's similiar to being in a restaurent when somebody chooses the "healthier" fish option without realising that the sauce contains more fat content than the rest of the menu combined.

        • No excuses, only laziness.

          Well, then as lazy programmers, we are all doomed!

          Seriously, this is really the bottom line - we have grown too comfortable with ignoring the nutritional value (or lack thereof) of what we eat. We've also "outsourced" our decisions to companies who really don't care about us, but about their profits. Put 'em together and it's a bad situation where we're creating a demand for Bad Food and it will only get worse.

          The South Beach Diet may be a fad, but at least it's creating awar

          • Yes, it is getting worse, for some, but the availability of healthy food for most. Even mcdonalds is starting to get its house in order and provide relatively healthy meals.

            You can get low-carb food in any health food shop or pharmacy along with the usual snake oil and trendy gimmicks.

            The brits are on the whole aware of what we consume, its just that many of us consume too much and have a drinking culture that adds even more weight.
