I dunno. The existing pattern matching code checks arguments against
predicates too. What is the class of expressions for which oppart works
and the existing pattern matcher does not?

We are talking about embarking on a project to implement some
substantial new functionality for the inverse Laplace transform. As we
start down this road, I am pretty much dead set against reimplementing
the existing pattern matching code in Maxima; there simply is no
justification for it. We may well discover that there are gaps in the
existing code for the purposes of this new project. When that happens,
it's OK by me to implement the stuff that is missing. What I'm opposed
to is reinventing the existing functionality.
