No back jumping in this forum.

It would be neat for you and me and other Python coders, but would be,
I think, noticeably more difficult for non-coders. Python, as clean
as it is, still has certain syntactic elements that don't really make
sense to non-coders, such as indentation and trailing colons. The
filter language today doesn't have conditionals, or nested block
structures, etc. and seems to be relatively easy for non-coders to
pick up. I'm not sure we want to require entry level Python skills
just to use TMDA.

I've been thinking about this for a while, but it hasn't been a
priority. I may have even mentioned it in the archives. I didn't
have any good reason to do this. It's definitely a possibility,
though.

Multiple rule matches would allow exactly this.

For the reasons above, I lean against requiring Python code, but ideas
on how to enhance the filter language have always been welcome. We
usually bash them around a bit in order to make sure we have the most
complete, simplest way to solve the problem, but the filter language
is not set in stone.
