Oh, one more thing, we probably need to handle nested levels too, for example, `foo(a);` might be triggered by a template which may be in turn triggered by the concept check. So only checking `S.CodeSynthesisContexts.back()` seems not enough. We need to check if we're in concept check context regardless of instantiation levels.
