Let me rephrase the purpose here:
So now clang instantiates a new function declaration as long as the previous
instantiation doesn't exist / the previous instantiation has a distinct primary
template declaration, right?
I feel I struggle to understand the benefit here, though it might indeed have
fixed/improved something. Can you explain it more?
