So I spent a little time looking into this. It seems 
assignToLvalue doesn't know how to deal with structs. I simply 
added this to dinterpret.d, around line 4026 (just before the 
"`%s` cannot be evaluated at compile time" block):

         else if (auto sle = e1.isStructLiteralExp())
         {
             oldval = sle;
         }

Now, is this a sufficient fix? I don't know. Does it break things 
elsewhere? I don't know. Does it work in this specific case, 
solving this specific problem? Sure does.
