[IPython-dev] IPyAutocall-like dispatching with simplegeneric

[Ville M. Vainio]

And more brainstorming... imagine if we got

@ipycmd.when_type(list):
def list_append(item, ip,iFun, rest):
 # check for 'list of strings, else raise ipapi.TryNext...
 item.append(rest)

Then you could accumulate a list by the shorthand:

l = []

l hello
l world

# l is now ['hello','world']

I bet you can think of quite a few enhancements like this, without
adding any code to core IPython itself.
