Interestingly, I also thought that something like this would work
now. I quite often have a few lines of code in a program,
which I would like to test interactively
(eg also after an ipshell call ...). Usually that code segment
is indented. To paste that part, I copy/paste it into a scratch
buffer of xemacs, do a rectangle select (eg. via mouse) and
then C-x r k  for rectangle-kill. Then the result can be
pasted into ipython.
I am not sure if it is possible to strip all " " automatically
from an input line (and the same number from the following ones)
until a double line break is encountered?
(I know that with readline this presumably cannot be
displayed properly, but still).

Maybe I should change my workflow, but this is presumably
the no1 annoyance ... ;-)
(We better don't talk about how I feel if I have to use a normal
python prompt - no time for this as I have to wade through
another 40 mails wrt scipy_core - aeh numpy ;-)

And I thought TABs are evil ;-)
