Indeed, in C++ template meta programming it is common to write code that will not be instantiated for types with certain properties with a technique called SFINAE. It looks a bit similar to me to the Scala example except that it is, as the name says, not an error; instead, a viable fallback or alternative is chosen by the compiler.

SFINAE was what I was thinking of, but I wasn't sure if that's actually what it was.
