       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.
