Thanks for testing, and thanks for pointing that out. I will fix it so that
`public` is optional.
btw, in your example you didn't have to specify `:classname` since you
defined the class name in the source block.
btw2, did you notice that you can C-c C-c on source blocks that don't have
main methods and it'll compile without error?
