I'm getting a lot of nothrow/@nogc errors where I would have expected the attributed to be inferred...

In particular; core.lifetime stuff, I can't live without that, but I'm finding that move and emplace are both often not inferring the nothrow and @nogc attributes correctly, and so they break my code.

Is this a known issue? Should I expect attribute inference to work comprehensively?

I've copy-pasted core.lifetime into my own library, stripped it bare and marked everything `nothrow @nogc`, and that works... but I'm not really keen to do this.
