Is there any method that doesn't require writing a custom parser? Is
there any standard way for solving a problem like this?
Honestly, don't use read. It's icky.

Check out ReadP or parsec, they are far superior in general. I think
there was a suggestion of replacing Read with ReadP?
The whole point is not about writing a parser, its about having a
