in reply to Interesting Use of Grep

Instead of a small golf or something clever, or cluttering the routine with a few lines, I'd favor breaking it out into its own function: 
if (in_list (@list, $my->{long}{to}{type}{variable}[0])
 {
 # do something...
 }

That makes it clear what I mean there, rather than having a maintainer have to reverse-engineer the code. Then in that function anything goes, since it's purpose is clear and a maintainer could just replace the whole thing.

    Good point. I think i think too much in the SQL i've been working with when I wonder why i can't just say

    if( $variable in  (LIST) )
{
  #do something...
}

      Really! There is a list module somewhere. But in general why limit it to == operation? A general select (map-like but not 1:1) would be good, and it can early-out in boolean context.
