OK. I can just about imagine how assignment to an ordinary scalar and assignment via an alias would be the same at run-time -- at run-time it doesn't much matter where the pointer to the SV has come from.

However, I would have thought that the two must be distinguished at compile time -- something has to take care of the implied dereference -- for no run-time penalty.

I realise that there are plenty of other traps for the new and the unwary -- but I can still remember the pain of learning about this one !
