Mmm... the issue with that exact approach is that we lose information:
once the AST is completely constructed, you can't tell which
declaration a DeclRef refers to.  Usually, it doesn't really matter;
however, a rewriting tool might be interested in knowing which
declaration is referred to, and we'd have funny cases where the type
of the DeclRef and the type of the Decl itself are different.  Still
might be workable, though.
