That works, though not because of the `=0` thing -- but because the compiler will nearly always call the sized version. It's not that easy to get it to call the non-sized version, but if we did, this would fail because this is an existing prototype that we have to implement. That's why I'd like to keep the non-sized version, even though it's not used right now.

I'll remove the argument name though...
