It's consistent. D's const is transitive, and D doesn't allow you 
to specify const on the indirection of a reference type. So there 
is no problem on the C++ mangling side of things, but, arguably, 
there is one in D's sementic, that isn't new.

Something like differentiating "const(C) i" and "const C i" may 
be a good idea.
