You bind the C++ extern to a D path, and as a result you get 2 
types because you have 2 paths rather than one. (according to 
what you have said)

If they mangle to the same name then I want them to be the same 
type.

As a result I am better off when using pure C++ frameworks and 
creating my own D layer than when I am using 2 mixed D/C++ 
frameworks that have been developed independently.

An therefore they should be seen as the same type!
