Hm, that's very interesting, I had no idea that part was open source. I'm a bit unclear on how it all fits together though, especially since I use Tango. I'm guessing the compiler inserts calls to certain functions in trace.d if it is invoked with the "-profile" switch? If so, where does that object code reside in my dmd installation? My dmd/import/std directory contains only very little stuff, and this doesn't seem to be there. So I'm guessing it must be in dmd/lib, but there is no phobos.lib there. Is that part compiled into one of the Tango libraries when I use Tango? If so, shouldn't that code be in the Tango repository somewhere too? Couldn't find it there, either.

Sorry for that slew of questions...
