recursive definition error

[Frustrated via Digitalmars-d-learn]

So, I took all the code surrounding the error message(which was a 
lot of code) and stuck it into one .d file.

No errors! Works as expected.

So, WTF?!?!

I guess now I have to attempt to split the code across modules to 
see WTF is going on? Maybe this is a modules issue. I know some 
of the code I'm using deals with module resolution and there was 
some talk in the main forum about changing something to do with 
modules.

Could this be the issue?

D really needs a better fing way to debug templates or improve 
the error messages. I'm dealing with about 20k lines of code 
spread across about 100 modules and the error messages are 
completely useless as when I put all the code surrounding what it 
says is causing the error, I do not get the error.

Realize, this code works fine in 2.064 so it's not a coding issue 
as if something magical with my fingers when I copy the code from 
the modules into a single .d file. Either something was "fixed" 
or something was "broke"... after all the work I spend trying to 
figure out what was causing the problem, I'm just as clueless.
