Perl::Critic::Policy::Variables::ProhibitConditionalDeclarations - Do not write my $foo = $bar if $baz; .
my $foo = $bar if $baz;
This Policy is part of the core Perl::Critic distribution.
Declaring a variable with a postfix conditional is really confusing. If the conditional is false, its not clear if the variable will be false, undefined, undeclared, or what. It's much more straightforward to make variable declarations separately.
my $foo = $baz if $bar; #not ok my $foo = $baz unless $bar; #not ok our $foo = $baz for @list; #not ok local $foo = $baz foreach @list; #not ok
This Policy is not configurable except for the standard options.
