I can get pretty far writing an application in Python with nothing more than
good command line support and syntax highlighting in any text editor.
Anything extra like completions, refactoring, etc, are just nice-to-haves. I

I don't have a Windows machine so I can't easily add Windows support. I'm

Windows, perhaps using BATCH scripts. Patches/pull requests are welcome :)

This is actually something that I am interested in doing (porting fixes from
trunk to 1.0) so I would love to help with that process

That still leaves open the question of how to decide which third party
libraries are OK to include as a dependency. That seems to require a more

the past clojure-contrib is the place for functions like the fast set
operations discussed here. This gives people a chance to use them and
identify any problems, etc before being considered for a move into clojure

Well, if you just want to print to standard out you could use print or
println. Apparently there's also with-out-file which I'm assuming
temporarily binds *out* so all output goes to a file. That might be the
