Re: [jruby-user] JRuby pitch for Java developers?

(Java was my college language and only briefly a profession language,
so these may be naive responses)

Hmm, being able to create 5 line scripts to do real work (especially
if stuck in a windows environment) is pretty nice. Relatively stupid
things such as, we have to copy files whose filename contains these
numbers and are of this file type with md5sum checks on either side.

Getting access to Ruby's Array and Hash. No more Java Vector ->
LinkedList -> etc. -> etc. to get map/reduce/delete_if functionality.
