Hi,
Been talking to someone on Telegraph and he was saying Ada should implement this, just wondering whether Ada could? I posed a slight change to access type specification to do this, what do people think?
type P is restricted access X;
Restricted in this case would mean that once assigned it cannot be re-assigned into or out of with out some sort of move operation, which could be implemented as an attribute on the access type.
A : P := L'Access;
B : P := A'Move; -- A cannot no longer be used.
begin
A.all ... ; -- raises exception.
I don't know enough about all this to put a complete proposal together, but I think I've got the basics understood.
Luke.
