You can see from the error message, the __dict__ on a Signal, simply
tries to pass the attribute *get* to whatever the Signal might be
containing. It does work on an object that does have a __dict__ but the
intbv doesn't have a __dict__.
class foo(object):
....: def __init__(self):
....: pass
....:
....:
In [78]: x = foo()
In [79]: x.bar = 1
In [81]: xs = Signal(x)
In [83]: xs.__dict__
Out[83]: {'bar': 1}
