Shriram Krishnamurthi has done work on macros that allow traceability 
back to the source code of the macro, but probably that won't be doable 
for string-generated code.

We need to devise a solution to that; for example, for each file blah.d 
that contains mixins, the compiler could automatically generate 
blah.d.expanded and make debugging info point into that file.
