It is one in practice. A language with a compiler that can not even inline
this trivial function:
test %rdi,%rdi
sete %al
retq
is not a viable alternative to C.
Not everything can or should be an enum, and D doesn't have macros -- there
is no workaround.
[That's "array.empty". More context, for people not reading the GDC list:

The bug may be hard to fix, and I really appreciate your effort, but this
definitely *is* a major problem.

Not if RVO is mandated by a spec. Yes, I had trouble with this in the past too. :)
IIRC an auto-return-type related problem was fixed by Walter some time ago; but I
still have to maintain the workaround, even after the bug has been fixed upstream...
