hmm, I know this is not what you've asked for, but
why would you want to do that? To me, it seems a pretty harmful idea
that only leads to confusion and does not provide sensible
functionality.
When S4 classes where created, using '@' instead of '@' with a
*different* meaning was very much on purpose and I think it's a
bit too ambitious to try being smarter than John Chambers,
the creator of the S4 object system, on this.
