By barneyb on June 26, 2008

Wanting some light reading for this evening, I decided to dig into the Closures for Java draft spec (homepage).
Oh. My. God.
I'm a huge fan of closures. They're elegant, simple, and easy to use. Their semantics are subtle, but not confusing. They allow for very concise implementation of otherwise complicated algorithms, [...]

</g:script>

CF Groovy

By barneyb on June 6, 2008

Those of you who remember CF Rhino will recognize the name for my latest little project. I whipped up a small proof-of-concept integration for Groovy into CF apps tonight while playing with some classloading issues within Groovy itself.
