It would be AWESOME if you could pass by-ref parameters using the ref keyword
(ditto with 'out'):
void foo(ref int bar) { ... }
int i = 0;
foo(ref i); // <------- here
and
void foo(out int bar) { ... }
int i = 0;
foo(out i); // <------- here
This should be an _optional_ feature, to avoid breaking code and to aide with
generics (saying 'ref' should, however, REQUIRE that the parameter be passed by
ref).
Why?
Documentation.
It documents the fact that you're passing something by reference, avoids bugs
where the variable is changed to be passed by value and the caller's code no
longer works, and making it optional allows everything to still work as before.
