I think I understood what the intent of your message was and even was going
to suggest a new keyword to assist with the context info, but when I thought
of some of the parse rules I'd written I could not imagine how any context
information issued from them would help me produce a meaningful response to
the user. So I unimaginatively said I don't think there is a general
solution. :^)

Hardly a problem. Perhaps just not always immediately measurably productive.
On the other hand such thinking is part of the creative search I'm sure.
