I am pinging the devel list, just in case someone might say something
about this issue. If not, I will post a bug at
https://bugs.launchpad.net/ipython/

cannot list their associated methods and attributes without assigning
them to names.

Some additional information, I use:

Linux ccn 2.6.27.19-170.2.35.fc10.i686.PAE (Fedora 10)

In [1]: [1,2,3].
Display all 104 possibilities? (y or n)

In [1]: {1:'a', 2:'b'}.
Display all 104 possibilities? (y or n)

In [2]: a = {1:'a', 2:'b'}

In [3]: a.
