[Numpy-discussion] numpy requires tuples for indexing where Numeric allowed them?

I'm fighting conversion from Numeric to numpy.

One change that doesn't seem documented is that I used to be able to 
select items using lists and now it seems that I have to convert them to 
tuples.  Is that correct and is there a function buried in there that 
will accept a list for indices?

Any reason that item() can't take a list?

The weird thing is that it doesn't blow up right away when a list is 
passed in an array ref but rather returns something I don't expect.

I work with lists rather than the implicit tuples of a function call 
because then I can work with arbitrary dimensions.

In the meantime, I guess I can just convert the list to an otherwise 
unnecessary tuple.
