Hm... neat idea. Somehow, opDispatch can probably be used to 
make this work even more generically (untested):

struct WithAlloc(alias alloc)
{
   auto opDispatch(string s, Args...)(auto ref Args args) if 
(__traits(compiles, mixin(s ~ "(args, alloc)")))
   {
      mixin("return " ~ s ~ "(args, alloc);");
   }
}
