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.
