Previously, Don stated that he thought that simply making it so that CTFE
didn't allocate a new integer every time it mutated it would be a _huge_
speed-up by itself (which presumably is what you're talking about with
regards to allocating new nodes). Unfortunately, he got too busy to actually
do that work and no one else stepped in to do. But if Stefan is going to
step up and improve CTFE, that's fantastic. It's one of D's best features,
but it's also one of its most problematic. Fixng that would be huge.
