shell and powershell pipes, haskell keywords mixed with the awesomeness of perl

 Perlude: If you're used to a unix shell, Windows Powershell or any
 language coming with the notion of streams, perl could be frustrating
 as functions like map and grep only works with arrays.
 .
 The goodness of it is that '|' is an on demand operator that can easily
 compose actions on potentially very large amount of data in a very memory
 and you can control the amount of consummed data in a friendly way.
 .
 Perlude gives a better '|' to Perl: as it works on scalars which can be
 both strings (like unix shell), numbers or references (like powershell).
