Perl::Critic::Policy::Community::LexicalForeachIterator3pm

Overview

It's possible to use a variable that's already been declared as the iterator for a foreach loop, but this will localize the variable to the loop and its value will be reverted after the loop is done. Always declare the loop iterator in the lexical scope of the loop with "my".

 foreach $foo (...) {...}    # not ok
 for $bar (...) {...}        # not ok
 foreach my $foo (...) {...} # ok
 for my $bar (...) {...}     # ok

This policy is a subclass of the Perl::Critic core policy Perl::Critic::Policy::Variables::RequireLexicalLoopIterators, and performs the same function but in the "community" theme.

Affiliation

This policy is part of Perl::Critic::Community.
