Hello,
I was talking to Walter on how to define a good study of D's compilation
speed. We figured that we clearly need a good baseline, otherwise
numbers have little meaning.
Might I draw attention again to this bug:

Granted, this is really freaking old. A re-application of profiling
should be done.
But in general, what I have observed from DMD compiling is that the number
and size (string size) of symbols is what really bogs it down. Most of
the time, it's lightning fast.
The reason the dcollections unit test taxes it so much is because I'm
instantiating 15 objects for each container type, and each one has
humongous symbols, a consequence of so many template arguments.
