Can you say a bit more about "negative precedence rules"?! A Google search
only revealed the page on Avail syntax stating "There is also a facility for
setting up precedence relations between operations (e.g., + and *) to assist
with disambiguation of expressions." but that's all I could find.

Thanks,
