What Pydev (will be inserted a little later, promised) calls Refactoring is quite a nice toy, but not too reliable.
I tried “Rename…“, and it does not rename keyword parameter usages.
I tried to use “Inline Local…” on an attribute getter, and it simply fell on its nose shouting “Could not translate editor coordinates into source node“.
Not really good enough for professional usage, not too bad for Open Source. Quite a good starter at least.
