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.
