• iterators? (Score:1)

  by dagolden (6584)

  Somehow, and surprisingly, none of the iterator type modules I saw in a quick CPAN seach do the trick with less finger pain. But there's always the option of $_ if you don't need the lexical:

  for ( @files ) {
    # stuff
  }

  For small scopes, I find I often revert to single letters.

  for my $f in ( @files ) {
    ...
  }

      Yeah. :-(

      I "got it" after I posted my reply and didn't even see it in my copy/paste.

  After doing some java coding, I often get compilation errors in perl because I forget the $ in front of a variable :).

  I can't think of any non-perlisms leaking into my Perl, but I find myself typing this all the time in C# :

    public ovid foo() {
      // ...
    }

    Ovid's foo should be private, thank you.

      I think you misread that. Anyone can ask foo() for an ovid. :-)

        What does it return in ovid context?

          What does it return in ovid context?

          It always returns ovid in an ovid context. In a strongly typed language, the compiler will never allow you to call it from a non-ovid context. I suppose you could overload foo() to return a virgil, horace, or even homer in other contexts, but I've never needed to do that.

            If any dead Greek poet were polymorphic, I would have thought ovid!

              He was considered a Roman poet, actually. Had Roman citizenship until he died, though he was never permitted to return to Rome after he was relegated (a form of exile).
• ok, but how to fix this? (Score:1)

  by notbenh (7967)

  I think that my most common 'non-perl-ism' would be 'elseif', easily fixable but still annoying, though that said I think that perl is a flexible enough base that we ~could~ address most of these (though ~should~ is a very different point). So, whats the next step? Do we write a bunch of editor hacks that clean up our fingers output? Do we start writing modules that allow for such errors to become valid?

  I have started adding the "in" also.
  I also wrote this once:
  
    my @list = for $i in @source when $i > 42 collect "OH, $i";


  It turns out that Perl can't parse that :)
