memoise: Memoisation of a parser
In kcf-jackson/combinatorParser: Build parsers with ease!

Description Usage Arguments Examples

This is used to tackle (infinite) left recursion in parsing, and it is done by memoising the input so that if the input is called twice with the same parser without evaluation, then an infinite recursion is registered.
