I agree, Groovy is not just way better than BSH, but also better than UEL too.
It might be a bit of a pain to change now, but I don't know. While designing
based on the idea of starting over I was planning on a move to "everything's
Groovy" to use Groovy for all expressions, scriptlets, and inline scripts and
scripts in separate files.
Of course, that brings up the question... why not just use Grails where every
artifact is a groovy script instead of having some artifacts as XML? Well, IMO
for many things XML is easier and cleaner for both writing and
reading/maintaining. If you don't like that, well, Grails isn't too bad as
frameworks go... :)
