Hmm, maybe. But right now if you used them, you'd get a linker error about a
missing function and can choose to remove the call or implement the function.
So in a way, it is "pay for what you use". With a compile error, implementing
it piecewise wouldn't be as easy - you'd have to drop the switch and go back to
writing a druntime port.

I think betterC should mean anything that works in C also works here with
little to no runtime support (matches C), anything which can work without the
runtime does (for example, scope statements, this makes it a better C), and the
rest can just continue to be a linker error so you opt in as you want by
implementing the functions.

This would also be the least work to implement in the compiler, since it is
leaving most things the way they are now.
