I'm loving this, my head is reeling with the glint of possibilities
import js
js.globals.console.log('hi!'*5)

Seems to be some issues with the interop still, eg:
import js
>>> "globals" in dir(js)
True
>>> "console" in dir(js.globals)
False
>>> js
<module 'js' (built-in)>
>>> js.globals.console
<js.Object handle=14>
So apparently introspection doesn't quite work with the wrapped js. Also, if you try: "[ i for i in js.globals]" (or equivalently iterate/loop over the globals-object) - the whole repl/tab hangs.Not really an issue for running business logic in the browser, but if this was a full python repl-interface (with ipython support!) to the whole browser DOM -- that'd be a fantastic tool.

The introspection bit is because js.globals is implemented with a fancy __getattr__ but doesn't have a __dir__. In general, dir() is not reliable in the face of custom __getattr__ implementations unless the implementor goes out of the way to make it work.
