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...

That's ok. The implementation is compiled into snn.lib
