I have redirected stdout through System.setErr() and System.setOut(), 
but I think it worked the same even before that. But providng my own 
print function isn't that bad.

I think it was mainly a misunderstanding from my side. I thought the 
interactive mode works like irb for Ruby or Python, like:

> 1 + 4
5
> foo()
"hello world"

But now I know it doesn't so I don't have to recreate it in my Swing 
shell. Too bad Lua doesn't have implicit returns :-)
