Ah yes, I'd missed the "string literal" part. In that case, I agree with
Niklas that quasi-quoters seem the best option. Although, they require
pretty much the same framework to operate (a custom data type and parser),
so once you have a quasi-quoter it's usually easy to implement dynamic
checks with the same tooling.

Yes. In Haskell, types are your friends. You should define new types liberally.
I believe the original poster was asking about a *static* check.
Newtypes with "smart constructors" are a good way to plug in a *dynamic* check, which is valuable but different.
