grep works just fine on arrays (and other lists). You live in a bizarre world if you interpret "grep works on arrays" to mean "grep is optimized to do something special if passed a single array similar to how foreach (in some versions of Perl) is optimized" (something that you can only detect by doing "weird" things). *shrug*
