Is SOMELIBRARY then reachable at all?
SOMELIBRARY basicPerform: #doSomething withArguments: (Array with:

Not currently. The reason is that Jtalk doesn't extend Object.prototype.
But as I said, Jtalk is still young, there are tons of things to do :)

No, you can call JS functions with:
        #basicPerform: and #basicPerform:withArguments:
