This patch fixes the problem (dmd r680):

====================

NOTE: I think the problem is that DsymbolExp::semantic() just returns 'this' if
it already run, whereas the function does elaborate AST rewriting. As for this
report's case, it rewrites itself to a VarExp *only* at the first semantic run.

So, the following patch also fixes the reported problem.
