Perl-Critic-Bangs

Changes for version 1.12

ENHANCEMENTS
- Removed Bangs::ProhibitUselessTopic, because it has been added to Perl::Critic as of version 1.122 as two separate policies, BuiltinFunctions::ProhibitUselessTopic and RegularExpressions::ProhibitUselessTopic.
FIXES
- GitHub issue #16: Bangs::ProhibitBitwiseOperators had default themes of "core" and "bugs". It can't have a theme of "core" because that's for Perl::Critic's own policies. It now has default themes of "bangs" and "bugs". Thanks, William Braswell and Oliver Trosien.

ENHANCEMENTS
- Added Bangs::ProhibitUselessTopic to warn against constructs like:
  - $_ =~ /foo/
- or my $size = -s $_;
- where the $_ is unnecessary.

ENHANCEMENTS
- The Bangs::ProhibitVagueNames and Bangs::ProhibitNumberedNames policies have been updated in much the same way:
- They now check names of subroutines as well as variables.
- Their checks are now case-insensitive.
- They only check variables or subroutines that you declare. They will no longer complain if you are forced to use someone else's poorly-named variable.
- NOTE: The functionality of checking subroutines is experimental. If it causes too many problems, I may remove it, or make it its own policy.
DOCUMENTATION
- Added more documentation about how ProhibitNumberedNames does its matching. There was nothing in there that said that if "utf8" was an exception that "foo_utf8" would pass cleanly.

A collection of handy Perl::Critic policies

Bitwise operators are usually accidentally used instead of logical boolean operators.

Commented-out code is usually noise. It should be removed.

Prohibit loading of debugging modules like Data::Dumper

Don't use XXX, TODO, or FIXME.

Know what you're going to test.

Prohibit variables and subroutines with names that end in digits.

Create a clone() method if you need copies of objects.

Adding modifiers to a regular expression made up entirely of a variable created with qr() is usually not doing what you expect.

Don't use generic variable and subroutine names.
