Yeah, the simple fact that you can't allocate exceptions in @nogc code is
crippling to @nogc, and a lot of code that could otherwise be @nogc can't be
because of exceptions - though the exception message poses a similar problem
(especially if you'd normally construct it with format), and I don't know
how you get around that other than not using anything more informative than
string literals. Unless I missed something, this proposal seems to ignore
that particular issue.
