There's a limited amount of support for arithmetic operations etc in the 'var' command, and I was planning on extending grep so that you could do substitutions (in addition to just matches) on environment variables, which would help a few text-crunching situations I've encountered recently. I don't have any plans (currently) to go beyond that.
