SYNOPSIS

DESCRIPTION

This policy is written by HAUKEX.

A grep with a constant value as the last thing in its block will either return all or none of the items in the list (depending on whether the value is true or false). You may have accidentally said grep {123} when you meant grep {$_==123}, or grep {"foo"} when you meant grep {$_ eq "foo"} or grep {/foo/}.
