Very cool. I've used that before and it is very fast. It's just not as flexible as I'd like. You had to pre-code the formula in such a way as to make the ("somefield","somealias") the last part. My SnippetFactory lets me inject any number of "parameters" anywhere in a forumla or snippet with the result being evaluated.
