Alright... These are my first stumbling steps into the glorious realm of
pydev scripting.
It's supposed to be a little helper for assigning the values of method
parameters to attributes of self with the same names, and it's activated
through "Ctrl-2" followed by "a<Enter>" ("a" for "assign"). Today it
quite happily displaces docstrings and probably also behaves badly by
other fascinating means which I still haven't discovered.
I'd appreciate any and all pointers I can get on all this, so I can
continue in the right direction.
Take care everybody!
