[Numpy-discussion] we held an impromptu dtype brainstorming sesison at SciPy

[Matti Picus]

The stars all aligned properly and some of the steering committee 
suggested we put together a quick brainstorming session over what to do 
with dtypes.
About 20 people joined in the discussion which was very productive. We 
began with user stories and design requirements, and asked some present 
to spend 5 minutes and create a straw-man implementation of what their 
dream dtype implementation would contain. The resulting document 
https://github.com/numpy/numpy/wiki/Dtype-Brainstorming will serve as 
the basis for a future NEP and more work toward a better, 
user-extensible dtype.

More comments are welcome, the discussion is only at the beginning stages.
