I'd like to make a suggestion for the regular expression in the greedy
completer. Prepending r"(?:.*\=+)?" should allow you to do things like:
since it won't include a=b= in the match.
I'm making progress on a custom completer for a dict-like object that doesnt

they are incredibly useful). I'll share what I have as soon as I tie what I
