[tpm] how to delete a list entry from within a foreach

[Fulko Hew]

I know this is probably simple, but I'm having a mental block,
and I can't find the 'easy' solution in any book right now...

If I'm foreach'ing over a 'pick list', I need to get a positive indication
that a match was found and then remove it from the 'pick list'.

something like:

if requestedvalue is on the picklist {
   remove it from the list
   return found
} else {
   return notfound
}

Being Perl, I'm sure there is an elegant way... If only I knew.
