There are distinct advantages to using a parser generator over parsing
combinators. For example, you get a static guarantee that your language
is unambiguous and doesn't need backtracking. (and we like static
I seem to recall there are parsing combinators that generate LR parsing
tables at runtime, which might be a good compromise though.
