"If a storage reference expression evaluates to a storage reference that is 
implemented by a variable, then the formal access duration of that access may 
not overlap the formal access duration of any other access to the same variable 
unless both accesses are reads."

That's exactly like ownership/borrowing. D does it in @live functions.
