No warning, error!
warning if it exist, error if used?
It probably should be an error. Then though, you have the unfortunate
thing whereby adding something to say struct X will shadow and generate
a compile error, which you can only fix by:
a) Not using with
b) rename identifier in your sturct
c) rename local variable
I seem to remember some language (I think it's VB) supporting with that
required a "." prefix in front of with enclosures. Like so:
auto a = 0;
with (foo)
{
a = 0;
.a = 1;
}
This is a bit dangerous too though, in terms of typos.
