Hard to say what the performance implications of Groovy are; it seems
like a Tapestry application spends very little time in user code; most
execution time is in framework code or in Hibernate/database access.
So I doubt Groovy will have a major impact. I'm building a T5 Groovy
app right now (you've seen some postings on my blog) and so far so
good, with minor caveats (bug fixes going into 5.0.14).
IDEA Groovy support is limited and a bit buggy ... and, I'm told,
still better that Eclipse support. To be honest, in terms of overall
productivity, the gains addded by Groovy are (so far) offset by the
clumsy IDE support and my relative unfamiliarity with the language.
Regardless, I want 5.0 to work with Groovy and in 5.1 perhaps add some
more involved support such as better handling of closures, optional
Groovy-oriented APIs, and perhaps a groovy: binding prefix.
