Re: [Visualpython-users] Let's hash out the documentation for restrictive imports

[Craig S. <cra...@ma...>]

I don't see vobjects as necessary, but maybe I am missing something. In every other Python module I've used, I can choose to either import module contents in its namespace:

import visual.primitives as vp

Or I can explicitly bring select functions, classes, etc. into the current namespace:

from visual.primitives import curve

I think anything outside the friendly visual package ought to behave like any typical standard Python package.

I also will add that Guy's proposal to make the clean version of the module be part of a different namespace (e.g. vpython, libvisual, visuallib [like matplotlib], or vispy [like scipy/numpy]) has merit. I do think it will be confusing and error prone to have the friendly visual module and the clean modules in similarly named name spaces.
