[PYTHON MATRIX-SIG] Let's get going

[Hinsen Konrad]

   3) Whenever a slice is passed to a function requiring a matrix argument,  
   automatically copy the data from the slice to a contiguous block of memory.   
   Allow slices to be used in numeric operations, doing this efficiently where  
   possible, and copying the slice to a contiguous block of memeory where not  
   possible.  This would be the most efficient solution.

Why would it have to be copied whenever it is passed to a function?
It would be sufficient to make a copy whenever the matrix is
changed.
