Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixeUserlContributPerl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators(3)NAME
Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators - Write " !$foo && $bar || $baz " instead of " not $foo && $bar
or $baz".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway advises against combining the low-precedence booleans ( "and or not" ) with the high-precedence boolean operators ( "&& || !" ) in
the same expression. Unless you fully understand the differences between the high and low-precedence operators, it is easy to misinterpret
expressions that use both. And even if you do understand them, it is not always clear if the author actually intended it.
next if not $foo || $bar; #not ok
next if !$foo || $bar; #ok
next if !( $foo || $bar ); #ok
CONFIGURATION
This Policy is not configurable except for the standard options.

Perl::Critic::Policy::ValuesAndExpressions::RequireUpperCaseHeredocTerminator - Write " <<'THE_END'; " instead of " <<'theEnd'; ".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
For legibility, HEREDOC terminators should be all UPPER CASE letters (and numbers), without any whitespace. Conway also recommends using a
standard prefix like "END_" but this policy doesn't enforce that.
print <<'the End'; #not ok
Hello World
the End
print <<'THE_END'; #ok
Hello World
THE_END
CONFIGURATION
This Policy is not configurable except for the standard options.

I'm just trying to confirm that I understand someone's code correctly.
If someone has code that says:
$foo ||= mysub();
I'm assuming that it means if $foo is nothing or undef, then assign it some value via mysub(). If I'm wrong on this, please let me know.
Also, what's the difference... (4 Replies)
