This is a quick hack based on something I once had to do in Python,
because Lua didn't have overloadable bitwise ops... until now! =D

Lpredicate allows the building of boolean expressions on predicates,
wich are basically lua functions wrapped as tables with some bitwise

even = predicate(function (n) return n % 2 == 0 end)
greater100 = predicate(function (n) return n > 100 end)

(even & greater100)(150) --> true
(even & greater100)(80) --> false
(even & ~greater100)(80) --> true

Code can be found at github:

seems interesting.

I'll check it so see whether I can integrate that into my unit testing infrustructure.
but firstly, I should test my code under Lua 5.3 :)
