Sommaire

NAME

Perl::Critic::Policy::Variables::ProhibitConditionalDeclarations - Do not write " my $foo = $bar if $baz; ".

AFFILIATION

This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

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

CONFIGURATION

This Policy is not configurable except for the standard options.
