[lldb-dev] How do you call complex methods from python?

[jingham at apple.com]

Enrico is the man for this sort of thing, but as I understand it, fancy argument conversions from the SB API's into Python methods are governed by %typemap swig directives, there are a bunch of these in scripts/Python/python-typemaps.swig.  But swig has default handling for C++ references, so I would imagine that you just make a python variable initialized to some ConnectionStatus enum value, and then pass that in.  Does that not work?
