I agree, of course. It's just that I like to test functionality extensions
by implementing them and discovering whether I continue using
them when the toy is not so new any more.

We may one day have LPeg in Lua itself. It was mooted by Roberto
as a candidate for 5.3. Enriching the present pattern syntax is not
supportive of that goal.
