What's the point in giving edir two modes if one of them is the same
as dir? You could just do "from module import edir" and then use
dir/edir as desired.

Personally I just use ipython's tab-completion instead of dir. It
shows the dunders if you first type underscores but hides them
otherwise e.g.:

In [1]: a = []

In [2]: a.<tab>
a.append   a.count    a.extend   a.index    a.insert   a.pop
a.remove   a.reverse  a.sort

In [2]: a.__<tab>
a.__add__           a.__format__        a.__imul__          a.__new__
         a.__setslice__
a.__class__         a.__ge__            a.__init__
a.__reduce__        a.__sizeof__
a.__contains__      a.__getattribute__  a.__iter__
a.__reduce_ex__     a.__str__
a.__delattr__       a.__getitem__       a.__le__            a.__repr__
         a.__subclasshook__
a.__delitem__       a.__getslice__      a.__len__           a.__reversed__
a.__delslice__      a.__gt__            a.__lt__            a.__rmul__
a.__doc__           a.__hash__          a.__mul__           a.__setattr__
a.__eq__            a.__iadd__          a.__ne__            a.__setitem__
