I'm a bit curious about what those bad experiences have been.  It's not
that I want you to use Pymacs, I'm not using it much myself :-).
Moreover, I could at least warn my users, and it might help python-mode
maintainers deciding about what's best for python-mode users.

Pymacs has some flaws, which I document in the manual when I learn about
them.  Some may be serious.  When signals get intercepted on the Python
side, the Lisp part and the Python part lose synchronization while
unstacking, while they should ideally unstack synchronously.  Threading
on the Python side may seriously mix things if proper care is not taken.

And more recently, I saw that Pymacs is useless at really inspecting the
state of a running program started though python-mode.  At least weaker
than pdb.  Completion is surely limited, would it be for this reason.

I'm not saying that Pymacs should be avoided, but at least, we should
try to have a clear mind about what it can and cannot do.  So yes, bad
experiences are worth reporting, too. :-)
