Unless I missed it, I think we still haven't answered the issue 
with throwing exceptions. I'm in particular interested in asserts 
and Errors.

Will "assert" be usable in @nogc code? Because if not, then 
basically *none* of phobos will be @nogc.

Also, I don't think statically pre-allocating the error is an 
acceptable workaround.

EG:

assert(arr.length, "arr is empty.");

vs

version (assert)
{
     static Error e = new Error("arr is empty.");
     if (!arr.length) throw e;
}
