[Numpy-discussion] Uncomfortable with matrix change

[Travis Oliphant]

Hi all,

I'm having trouble emailing this list from work, so I'm using a 
different email address.

After Nathan Bell's recent complaints, I'm a bit more uncomfortable with 
the matrix change to scalar indexing.   It does and will break code in 
possibly hard-to-track down ways.   Also, Nathan has been a *huge* 
contributor to the Sparse matrix in scipy and so I value his opinion 
about the NumPy matrix.  One of my goals is to have those two objects 
work together a bit more seamlessly.

So, I think we need to:

1) Add a warning to scalar access
2) Back-out the change and fix all the places where NumPy assumes 
incorrectly that the number of dimensions reduce on PySequence_GetItem.

Opinions?
