Have you considered rolling your own parser?
If you don't want say the expression parser or the language defs,
quite a bit of Parsec's machinery is now standard-ish. For instance,

I can easily see how one identifies the domain and co-domain of a unary

How would the domain of a function be expressed that takes more than one
