Changes to Block Behavior?

Please see the main page of the repo for the actual RFC. As it states there:

Anything in the Wiki should be considered "rough drafts."

Note: The proposal has been rescinded.

Inside of a Corinna class, or a hypothetical module keyword (similar to Corinna, but for procedural code), we can "fix" some things about Perl.

class Some::Class {
    # different core behavior here
}

module Some::Module {
    # different core behavior here
}

But what should those fixes be? Having strict and warnings on by default seems rather uncontroversial, but what else? We should try to get some agreement here. A first pass, obviously inspired by Perl 7 discussions:

use strict;
use warnings;
use utf8;
use open qw(:std :utf8);
use autodie ':all';
use feature qw(signatures say);

no warnings qw(experimental::signatures);
no feature qw(indirect);

no multidimensional;
no bareword::filehandles;

The "signatures" is a touch odd because method signatures don't include the $self:

method foo ($bar) {
   return !!$self->baz($bar);
}

Probably not a big deal, though.

The autodie might surprise some, but it seems like a good thing.

For a module keyword, the signatures might be a big odd due to the prototype issue, meaning we might not be able to dual-life this for versions of Perl prior to 5.20.
