  • You could just make it configurable and give it a decent default. This particular piece of functionality seems like it could be good for Perl::Critic as well.
    • My only concern is that it turns out to be misleading. I don't want to be seen promoting shorter methods if it turns out they're not actually a good idea. Still, if I can make it work more reliably, I will try that. If I can't make it work reliably, then it's a moot point :)

      • Well if you encounter a very long method, it's probably not bad in general, it's probably bad for specific reasons, like:

        It's doing more than one thing, and the things are probably unrelated (which also makes it more difficult to name properly).

        Even if they're not unrelated, it's a missed opportunity to write self documenting code by giving the functionality a (method) name. There are probably documenting comments in there to demarcate the functionality anyway. If not, there should be. Well, unless the meth

        • I agree with all of this and it's the reason I included this code smell. That being said, the research seems to indicate otherwise. The subjective experience of many programmers seems to be contradicted by the objective experience of quite a few studies on the subject. See Code Complete 2 for a full list.

  • As a side note you may wish to electively reduce the penalty of whatever "long" is if its broken up with labelled blocks. They're not necessarily *as* good as breaking it into smaller functions, but for cases where you would otherwise call the function only once I consider it an "acceptable" alternative.
    • I don't know how to identify labelled blocks without PPI. That being said, given that the "long method" code smell turns out to be rather bogus, I'm not overly inclined to go much further there. Interesting point, though.
