All this talk about including new operators, keywords, etc. makes me
wonder about the possible inclusion of token filters, a Lisp-like
macro system or other metaprogramming facility in the next major
release. It may give an answer for all these "Lua do not have my
favorite operator/statement/conditional construction/etc." questions,
perhaps at the cost of generating some Perlish monstrosities like
Lingua::Romana::Perligata [1]
