(++) : ('a -> 'b * 'c) -> ('c -> 'd * 'e) -> 'a -> ('b * 'd) * 'e

SYNOPSIS
Sequentially compose two parsers.

DESCRIPTION
If p1 and p2 are two parsers, p1 ++ p2 is a new parser that parses as much of the input as possible using p1 and then as much of what remains using p2, returning the pair of parse results and the unparsed input.

FAILURE CONDITIONS
Never fails.

COMMENTS
This is one of a suite of combinators for manipulating ``parsers''. A parser is simply a function whose OCaml type is some instance of :('a)list -> 'b * ('a)list. The function should take a list of objects of type :'a (e.g. characters or tokens), parse as much of it as possible from left to right, and return a pair consisting of the object derived from parsing (e.g. a term or a special syntax tree) and the list of elements that were not processed.
