What happened to the scope storage class for parameters.
Wouldn't this solve the problems, with the simple rule that
you are
not allowed to pass transient objects by reference if the
parameter
was not declared with scope? And if I understood correctly, the
compiler is already capable of locally ensuring that the
address does
not escape (to ensure the scope requirement), so we are all
set?
This is an important question. How would this new proposal
interact with
scope parameters?
scope in not enough, as you can alias parameters (for instance
swap).
