The discussion is how a Function without any generics (raw) should be
treated.
In general we have 3 possiblities:
- Skip input validation completely if Function implements
ResultTypeQueryable
- Introduce a Interface /Anntotation SkipInputValidation for special use
cases
- This PR: Skip input validation if Function is a raw type.
> Allow KeySelectors to implement ResultTypeQueryable
