In my project compilation takes now several minutes for some files

I'll try to track this down when I get the time, but i doubt that
those times get anywhere near those of the original.
Do you have modules that recursively import themselves, and instantiate
a lot of templates?
There were some import cycles and I've had some time now to remove all
of them. There might be a small improvement but it feels just as slow as
before (still multiple minutes for some files).
In the particular region of the library there is a Variant template in
use at two places as a typedef: "typedef Variant!(TypeEnum, type1,
type2, ..., type8);". This would be my main suspect when it comes to
templates. However, compiling the Variant module alone or a small module
only using Variant takes a fraction of a second.
I have attached the output of a CodeAnalyst profiling run. The file
shows the hotspot section during the first 60 seconds of compiling one
of the files. Percentages have to be multiplied roughly by 2 because
this is a dual core system.
