Not quite, but it has some extreme oddities. I'd have to call them
features because I can't imagine them to be bugs, but they're very
surprising... like how you can recall something, but if you enter it
without any editing, your "current recall position" is retained. This
means you can re-enter a series of lines by recalling the first and
then pressing Down, Enter for each subsequent line (it's a feature!),
but it means that any usage where the lines are truly independent will
start getting very awkward.

In contrast, Idle recalls entire suites, rather than individual lines,
which (IMO) makes it superior to a readline-based interface.
