Things like var_id(), and other reflection like techniques are more likely to surface when we get into dynamically evaluated code. It might be a reasonable workaround for a more native implementation of PBR.

var_id() has a potential problem that routine_id does not have: What if I take a reference to a variable that is allocated on the call stack? The variable disappears after the call, but how is the reference invalidated? Other pass by reference syntaxes do not necessarily have this issue.

True. That's another area that has to be thought out before it could happen, and just for reasons like that.
