debug mixins

[Inquie via Digitalmars-d-learn]

So, is it possible to debug string mixins?

I ran visual D and tried to step in to a function that was 
generated by a mixin and it brought an open file dialog box 
asking me to load the source code where the function was 
located... of course, it wasn't located anywhere except in the 
mixin string.


This leads to the idea, why can't the compiler simply output the 
mixin string to a file then the debugger can load that source 
file?

One of the most frustrating things about D is not having the 
ability to debug it's powerful meta programming in any reasonable 
way. (bad enough having to resort to using pragma(msg))

But we can't even debug the results of those meta programming in 
the case of string mixins because there is no way to step in to 
them... It seems all the machinery is there, but just a few extra 
steps are needed.
