This is probably because the diagnostics are not in the "immediate context"
of the substitution (that is, they're not diagnostics that a SFINAE check
can detect, they're hard errors). We don't have a way to suppress those
diagnostics and return to a state as if the instantiation never happened
(the C++ language doesn't require such a mechanism). After such a
diagnostic occurs, parts of your AST might be marked as "invalid", and we
might suppress further diagnostics (possibly resulting in a later
instantiation succeeding when it would have failed if run from a clean
state). If you're OK with that, I think there's a flag on the
DiagnosticsEngine to suppress *all* diagnostics.
