I just meant it's not recommended for plugins to rely on the tree view 
implementation stuff like which tree model columns have various things 
packed in them and such just because it's undocumented and could change 
anytime. Anyway, you are of course free to do anything you want, and if 
that's the only way, what else can you do? :)

It should be in the "current" library (not sure correct term), like if 
it was C, you would call `dlopen(NULL, ...)`. I'm not familiar enough 
with ctypes to say exactly but if it had a function like 
`load_library()` I'd expect you would pass `None` where it expects a 
filename. Alternatively, you might try `geany.document.__file__` to 
pickup the C module's filename where the symbol lives, if that works.
