Looking for syntactic shortcutby mrd (Beadle)

mrd has asked for the
wisdom of the Perl Monks concerning the following question:
I'm looking for a shortcut to extract a specific element out of an array without using a temporary variable. The array is returned by a function and I only need a particular element of that.
Since a line of code is worth 2000 lines of plain (gibberish) text (of mine), here is what I do:
Only I want to do it shorter. Something like:
which obviously doesn't work.
PS: I could wrap function() in another function that returns the element I want from a local array. But that's just too much work :)
PPS: I'm sure it's been discussed before but I can't seem to come up with an adequate search expression.
