I suspect a lot of perl users don't  have a great deal of familiarity  
with functional languages where list processing is emphasized than it  
is in perl -- lisp, scheme, the MLs, and so on.  map, filter/grep,  
and one that perl's missing as a built-in -- fold (which can be used  
to create pretty much any other list function) are used all over the  
place in those languages. Not so much in perl, though not for  
technical reasons. People get into a certain mindset of how to do  
something and just don't think of alternatives using other paradigms  
or idioms.
