Hi,

you should not need any customization for IPython.
There was a bug, which shold be gone now. Could you try from current
trunk again?

Made a bug report lp:927136 for this. Let's continue there, should
something being left.

thanks for your report,

Andreas

Nah, doesn't work. Regarding how to proceed on this: I'd prefer
to write down (in an .org file) what configuration causes which
problems at specific places in python statement, i.e.:

This configuration
#+begin_src elisp
  (add-to-list 'load-path "~/.emacs.d/python-mode")
  (autoload 'python-mode "python-mode" "Python editing mode." t)
  (setq py-shell-name "ipython2")
#+end_src
causes this
#+begin_src python
  import numpy as np
  np.[M-TAB]
#+end_src
to lock emacs indefinitely.

This should reduce the chance of misunderstanding, especially since my system
might be different from yours (python and ipython are both Python 3 here). It
also makes it easier for me to allocate time and is likely to reduce the amount
of time to fix this issue on your side as well.

I hope you're ok with this.

AFAIU completion should return here all the symbols of np? Right?

For now it's implemented as a kind of word-completion, expecting some
chars of it already inserted.
