Well, you just execute the file that contains the public class in a VM.

Foo bar;

public class Foo
23 => int value;

now B is only going to compile if you run A (and thus define Foo) first. Not
very hard, I'd say.

Also, no, currently chuck doesn't have a way to import libraries

True. If B.ck would read;
Foo bar;

It wouldn't work as B would be parsed (finding a undefined class) before A
would be Machine.added. So; one possible solution to this would be a
Machine.include() command that would see whether the classes in it's
argument are already defined, if not define those and only then parse the
rest of the file. That's not without problems as a way of fixing the issue
though and if available I'd support a more intelligent method.

Also, once added a public class can't be edited, for example to add some
feature to it, without restarting the whole VM.
