Suggestion: Sugar for call-attr and call-attr-kw about libpython-clj HOT 6 CLOSED

Thank you, my hope is to allow clojure and python to deeply intermix and give both python and clojure people incremental and efficient pathways to work together.

I completely agree about syntax. I would personally vote for building out namespaces so for instance a numpy namespace. Let's see if anyone else chimes in.

This issue is solved by Alan Marazzi's panthera.

Just about syntax, we could inspire ourselves from Hy (lisp for python), for function call:

http://docs.hylang.org/en/stable/tutorial.html

They use a #* and #** for the python equivalent.

The general direction I like. Some sugar around keyword arguments would be nice; I think it might take the form of a macro or something that analyzed the argument types and if there were an odd number of arguments after the first keyword argument would default to call-kw.

This:

(optional-arg #* args #** kwargs)
[1, 2, 4, 3]

Would expand directly to:

(call-kw optional-arg args kwargs)

What we don't have is the python compiler deciding what goes in the arglist and the keyword argmap; I believe this would have to be done by a macro.

I should add that I know Alan has experimented with a couple different directions here and he is still working on it. I think Panthera has a couple motivational examples.

I still believe that modules should have the namespace syntax, but I like how Alan solved the problem for numpy.
