Still does not give a default does it? How loopy these APIs can be :(

Thanks Allan, you basically wrote everything I needed.
You even reminded me implicitly that passing 0 or 0.0 gives a default size.
Good callout about which Python to use.
Specifically, regarding the PyObjC part, though older, it is more integrated than the non bundled PyObjC in a few subtle ways.
Most people will need to know that.
The bridge is older but is the one built and used by Apple. 


What are the best options for displaying the completions?
Some implementations on other editors these days are showing some inline docs snippets along with the completions.
Is that sort of thing feasible under the current TM architecture?
