In every case these situations would be easily solved if I could specify "Generic != CertainType" in the where clause of one of the overloads so I can disambiguate the cases. Could this be added to language?

+ all the 1s, along with something like "where !(T: Foo)"

IIRC, the topic has come up before, though I couldn't (quickly) find it and don't recall what the response was (other than some variation of "no", since we don't have it).
