A way to detect a ref parameter

[downs]

Is there any way to detect if the nth parameter of a delegate type or function pointer type is ref, or out?
(short of scanning the mangleof, of course)
If not, I vote the language be changed in 2.0 to allow this.
It's very annoying to be completely unable to wrap delegates that contain ref, while maintaining their functionality.
One way I could see is to turn ref into a storage type, and add a way to detect it via templates.
Please?
