Hasnt been swigged. This would be neat because the errors could pop up
in a little message window in the GUI.

No. Its more of a global process thing, rather than a per instance.
This is basically a swig directors use case, and there isnt any public
header c++ header stuff to expose. You are basically looking at a custom
handler in the .i file,
and a little routine in the init.py
I'm not in a state of implementing it right now, but if you want some
inspiration, the python blocks code uses the existing gnuradio swig
director stuff, you should take a look:
