Formally, an access parameter has mode "in" ("access" is NOT a parameter 
mode), so this is definitely not exactly obvious.

There is a (brief) discussion of this idea in AI05-0144-1; it was rejected 
as not really solving the problem at hand. (Which is not the same as saying 
that it doesn't solve ANY problem.) I know there was an e-mail discussion on 
this idea as well, but I haven't been able to locate it.
