=head1 DESCRIPTION |
19
|
|
|
|
|
|
|
|
20
|
|
|
|
|
|
|
It's possible to use a variable that's already been declared as the iterator |
21
|
|
|
|
|
|
|
for a L<foreach loop|perlsyn/"Foreach Loops">, but this will localize the |
22
|
|
|
|
|
|
|
variable to the loop and its value will be reverted after the loop is done. |
23
|
|
|
|
|
|
|
Always declare the loop iterator in the lexical scope of the loop with C<my>. |

foreach $foo (...) {...} # not ok |

for $bar (...) {...} # not ok |

|
|
|
|
|
|
|
foreach my $foo (...) {...} # ok |
28
|

|
