/// @assertion We do not allow dynamic explicit instantiation. If an expression
/// e has type dynamic (or Never), then e.foo<int> is a compile-time error for
/// any name foo. (It'd be valid for a member of Object that was a generic
/// function, but none of the Object members are generic functions). It's not
/// possible to do implicit instantiation without knowing the member signature.
