It would be nice if there was a maintenance release with 
the patch by piro, since this bug affects all global names, 
i.e. all builtin names.

Since (boh) the module "keyword" chenged: there is no more a
dict called "kwdict". The following patch fixed the problem.

actually there is a difference w.r.t. the attribute
behaviour: if i define "aaaaa" and "aaaab", pressing
"aa<tab>" shows the possible completions, but it doesn't
complete up to "aaaa". When the prefix is not ambiguous, the
word is fully completed.

btw, is this project still alive?

 def docstring(obj):

After importing rlcompleter2, hit tab at the >>> prompt. A
list of the entries in the global namespace. Which is good.
But try something like:

>>> import sys
>>> sy<tab>

and nothing happens. I would expect that the tab either
completes the sys or that the list of items in the namespace
that start with sy would be displayed.

For contrast, if you type

>>> sys.m<tab>

the list of items in the sys namespace that begin with m is
displayed. Typing:

>>> sys.mo<tab>

will complete the text as sys.modules.

It would be really nice if the rlcompleter2 worked the same
at the global level as it does at the module level.

BTW, this is seen running Python 2.4.1 on a Ubuntu 5.04 system.
