High performance code should never have exceptions in the fast
path. The code gen is heavily and unapologetically biased
towards speed in the non-exception path. This is true for C++
and D.
Right, but that doesn't mean the slow path should become all the
more slower for codebases that do this. I haven't, but if I had
I'd imagine I'd be none too happy about it.
