hacks?
They have, fer instance, PFE, which gives them precompiled headers.
I can confirm that, when used, it compiles at least twice as fast.
It's not a hack, i've looked at the code before.
I'm sure if Geoff Keating looked at it, he'd tell you the way it's
implemented is the reason gengtype was invented.
