It's on my list of things to get round to. I think what I'm really after though is a parsing DSL. I only did only one fairly small project in SNOBOL but I was impressed at the ease with which I could express the problem (some googling suggested that many end users found the same). I guess I want SNOBOL embedded in a modern language with scoping etc. Python is antithetical to (this class of) DSLs (IMHO) :( Probably what I really need is parser combinators in Haskell or maybe camlp4 or some such exotica but unfortunately I've never heard of them.
