Build times with the new dsss push me way past the sanity point, so
I've gone back to 0.76, which I think may have never been released.
I think I built it myself from sources.
Build times with 0.76 are just barely tolerable with my app. But my
colleague was telling me today that he wants to do his work on a
small, non-DWT test app instead of the main app because the build
times are too frustrating for him.
If I were forced to use the latest DSSS, I'd defnitely be trying to
do whatever I could to improve the build times, including using
"make" if that's what it took.
Hmm... Now that dmd -v will spit out all the modules imported, it
might be possible to use that to create a makefile (or a make.deps
for use by a makefile) automatically.

I didn't notice dsss has such a large overhead, is this due to dsss
parsing the whole source, or has it something to do with how it
compiles applications? If it is the latter, perhaps that's amenable
with some configuration?
Dsss does multicore builds, that probably cancels out the overhead on
my machine.
I'm not sure what the reason is, but I imagine the re-parsing is only part
of it because dsss 0.75 is actually pretty fast (compared to release 0.78).
I think I remember Gregor suggesting that performance could be improved (or
at least dsss could be simplified) if he had access to a new feature in the
dmd compiler ("-ignore" flag: ignore unsupported pragmas). That feature
was added several versions ago, but I think Gregor has been too busy to make
use of it. I can't remember how using this flag could fix things for dsss,
though. The answer lies somewhere in posts from earlier this year.
