Mondo Monks,

What is the cleanest, most simple, way to do this:

If x='key_1', execute the following block of code for every key in %my_hash. But if x != 'key_1', execute that block of code for just that single key of %my_hash.

For example, this would do it, but it's clunky:

%my_hash = ( key_1 => $value_1, key_2 => $value_2, key_3 => $value_3, key_4 => $value_4, key_5 => $value_5 ); foreach $key (keys %my_hash) { if ($x eq 'key_1' || $key eq $x) { do a bunch of stuff; } }

Thanks
