21.5 says:

`ignore-errors' is a compiled Lisp macro
   -- loaded from "cl-macs"
(ignore-errors &rest BODY)

Execute BODY; if an error occurs, return nil.
Otherwise, return result of last form in BODY.


That should work.

BTW in cases, XEmacs misses a form, think it's better to implement it 
for XE as we have done, rather than maintain python-mode specific forms.

Sure :-)

Code was more verbose without it, so I do think it

Listen, Barry: the code is intrinsic for me to an extend, that I don't 
know how to fix the remaining bugs mentioned. All these bugs are absent 
in the components branch, because it's simplified from the scratch - 
more or less...

Tried to backport some solution and could resolve some issues. But again 
and again going trapped into some wire.

Obviously no one else could solve that over the years also. That's not a 
surprise. We are in some labyrinth, before some gordic knots.

OTOH it's a pleasure for me to see solutions from different sides, 
python.el, components- and python-mode. So if you permit, will try to 
range things still.

Tell if cannot bear it any longer :-)
