Good find but its effect in overload resolution is an oversight.

The uniqueness of an expression should not interfere with overload 
resolution because overload resolution does not involve expressions but 
their types. Otherwise, a simple change in an object initialization 
takes us to a different function. A different kind of hijacking indeed...
