I made a module that looped for a while in compile time (since you can't
sleep during compile time), to see if I could pre-compile the module,

first, because any file that depended on the module would import it, and
importing it would execute the compile time code again, thus taking a
long time to compile... twice.
But then I remembered about the rarely used -H option for dmd. -H
outputs a stripped down version of the source file being compiled, with
all the function definitions replaced with declarations. So if your
expensive to compile code is encapsulated within a function... it
doesn't appear in the -H output.
So uh... git://critter.cloudns.org/test-dlang-encapsulation I guess. It
might be a neat trick to speed up compilation, if you have a lot of
complicated code that can be hidden behind a simple interface.
Sounds like a use case for creating a source file in a pregeneration step.
