I have complex template that uses a mixin to solve some problems.
The mixin produces the error. I thought template's were added in
to the scope of the call? I guess the mixin is inserted before
this happens. That isn't good ;/
Here is one place the error happens
mixin("alias Func = extern("~functionLinkage!Q~")
"~(ReturnType!Q).stringof~"
function"~(Erase!(Parameters!Q)).stringof~";");
The mixin is required to get the proper linkage, as no other
method has been found to do that. Everything works with built in
types.
I saw somewhere that vibe.d had some way around this but the
links are dead.
