use 5.011/5.012 should be progressive

Arador on 2009-08-22T16:10:41

As some may know, use 5.011 activates strictures. I think that's a good idea, but I don't think that's enough. I strongly feel that it should be more progressive than that. I think it should do what Modern::Perl aims to do implement: Some small, important and uncontroversial pragmas (as opposed to Perl 5i, which does do big and controversial things). My list of things would be:

  • use feature '5.011';
  • use warnings;
  • use IO::Handle;
  • no indirect;
  • use mro 'c3';


Anyway: I'd like to hear what other people think use 5.011 (and thus eventually use 5.012) should mean.

use 5.012

It already does "use feature '5.011';". And it was hard to add even "use strict" - too much opposition. "use warnings" would have even more.

Sorry, no

Strongly disagree with IO::Handle and warnings. Strictures are important, warnings are not (note that I almost always enable them).

Would like no indirect, but I doubt it’ll happen.

Not opposed to C3, but indifferent.

What's wrong with IO::Handle? 5.6 could have supported calling methods on lexical filehandles without loading IO::Handle explicitly without violating the Principle of Least Surprise. (I could argue that having an object you can't actually call methods on violates PoLS.)

use warnings FATAL => 'all';

I've been doing this for years in code without any problems, so I think it's a good candidate if strictures are going to be enabled.
