Important, because `__getattr__` and `hasattr` catch AttributeErrors
implicitly. This is really evil (mainly because of `__getattr__`).
Therefore this class originally had to be derived from `BaseException`
instead of `Exception`. But because I removed relevant `hasattr` from
the code base, we can now switch back to `Exception`.

Re-throw uncaught `AttributeError`.
Usage: Put ``@rethrow_uncaught`` in front of the function
which does **not** suppose to raise `AttributeError`.
AttributeError is easily get caught by `hasattr` and another
``except AttributeError`` clause. This becomes problem when you use
a lot of "dynamic" attributes (e.g., using ``@property``) because you
can't distinguish if the property does not exist for real or some code
inside of the "dynamic" attribute through that error. In a well
written code, such error should not exist but getting there is very
difficult. This decorator is to help us getting there by changing
`AttributeError` to `UncaughtAttributeError` to avoid unexpected catch.
This helps us noticing bugs earlier and facilitates debugging.
