I think this is a marvelous idea.
I actually started working on a JSTL-ish set of tags based on the Groovy
expression language because AFAICT the Groovy expression language is a
perfect superset of Velocity's. The main reason, though, is that Groovy
has a nice API that lets me evaluate expressions directly so it's easy.
I'd be perfectly happy with VSTL instead of GSTL... it's just a question
of a nice API for evaluating expressions.
I just noticed this:
http://jakarta.apache.org/commons/jexl/index.html
if you look at the javadocs, you can see it's not just
Velocity-inspired but is basically a fork of Velocity. Not sure how
best this would fit into a VSTL idea, but it's certainly something we
need to look at.
