Memoisation is a technique for making backtracking parser performance linear over the input length at the cost of higher memory consumption and more overhead for less exponential grammars. It would be nice to be able to support it.

Closing because #290 implements a memoisation combinator. However, I still believe there's a need for improved behaviour: it can be unintuitive to figure out where best to place the combinator right now.
