[Numpy-discussion] still no cross product for new array type

Just browsing through the new array PEP to see if there's support for 
3-vector operations, such as cross product, norm, length functions. 
Sadly I don't see any. It's something I think is lacking from Numeric 
and numarray and would like to see implemented. Is it a deliberate 
choice not to include any? I understand that vectors are sufficiently 
different animals that you could argue that they shouldn't be supported. 
I use them enough to think that they should be.
