Hi,

I like the idea, but having multiple implicit solvers might create
confusion.
If I were to use such a feature, I'd see myself constantly re-checking docs
to see if I have the correct one.

Would something more explicit, like something close or similar to regex
named groups possible to circumvent such a confusion?
