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
ops:
--
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
