To simplify it part a) of my previous email:
def tester(d):

from json import loads
bar = loads('["foo", {"bar":["baz", null, 1.0, 2]}]',
> object_hook=tester) self.mainPanel.add(HTML(bar))
On the browser:
> ['foo', {'bar': ['baz', None, 1, 2]}]
It looks like loads works, but the object_hook parameter does not. I can
see the tester function being mapped in the browser debugger. But I am not
sure where it breaks. its kind of hard to follow whats going on. Just
wondering if we are going down the right path here..
