OR when the patch that will receive the message is not the same one (or a subpatch of the one) in which you generate the message; that is, if "$0" evaluates to different values in the two contexts.
This is possible, isn't it? This wouldn't necessarily involve saving....

However, I think an escaping mecanism (at least for $'s in messages) would indeed be vital.
WHENEVER a special character exists, an escape character should exist, just in case.
