[IPython-dev] IPyAutocall-like dispatching with simplegeneric

[Ville M. Vainio]

And the stream of consciousness goes ever on...

We could also use a generic function for custom completers, something like:

@generic
def ipycomplete(item, event):
 raise TryNext


cd = object()

@ipycomplete.when_object(cd):
def complete_cd(item, event):
 # return a list of dirs, like with current custom cd completers...
 ...

This would again allow more elegant way to add completers than the
current registration approach.

Of course objects like this 'cd' should not be shows by %whos in order
to not confuse the user with too many variables.
