Yes, I wouldn't want to use it, maybe manual mangling is
better, but still painful. ```const A&``` is so common in C++
API's that it really should be supported out-of-the-box. All
it takes is adding a deref-type-constructor to the D language
spec, e.g. ```ref const(@deref(A))```
I fully agree. This pattern is so common in C++, that I am
surprised D doesn't have a way to do this already. The whole idea
of linking against C++ is to interop easily, with little friction
and high performance. Needing to build any shims or redesign the
C++ side is very much contrary to this goal.
Does anyone know whether such issues have been discussed before?
I can't imagine I'm the first one to run into this.
