Re: [aspectj-users] AspectJ + Groovy?

[Jim Bethancourt <jimbethancourt@xxxxxxxxx>]

Hi Ron,
Thanks so much for the reply.  I haven't had a chance to use Groovy
any, but wanted to see about what other people have done and if it
would be worth persuing.   I guess I might go ahead and try a little
bit down the road (once I learn Groovy) and see what I can do.  If I
have any epiphanies, I'd be happy to add them to the docs and best
practices if you'd like.

Yours truly,
Jim
