Remarks
ParseResult Cases
A ParseResult comes in three flavors:
Success, with a marker as to the start of the match and the next character to be matched.
Failure, with a marker as to the start of where the match was attempted. In this case the parser backtracks to that position, where it will be when parsing continues.
Error, which stops the parsing. No backtracking or further parsing occurs.
