[antlr-interest] Filtering peer nodes in a tree

[J. Stephen Riley Silber]

> I tried using a rule like ^( BLOCK .* ASSIGN ASSIGN .* ), but that didn't seem to work.

I've recently discovered that .* on the end doesn't seem to work too well. I think I tried .+ or was it .* followed by UP...no, i think it was ~UP*. I need to fix this.

I just tried all of those, to no avail.  Is this a legit bug?  Am I on the right track for trying to detect similar siblings?
