Should out/ref parameters require the caller to specify out/ref like in C#?

Since scope was never properly defined for anything other than delegates,
it's questionable that _anyone_ who used it used it properly. But
regardless, nothing will break because of scope-related stuff unless you use
the -dip1000 switch, which would then require scope in a number of places
that it wasn't before (including on local variables in a number of cases
IIRC), making it so that even if in had stayed const scope, pretty much
regardless of how you used it, code would break (which is going to make life
fun when when we finally transition from dip 1000 to being optional to being
the normal behavior).
