I hope to be able to make a new release this or next week.  So far, I
think objects implementing the buffer interface should *not* be allowed
as function parameters, but *buffer objects* should be.  The reason is
that the former would break too much code.

IIUC, you should then be able to call buffer() on a Numeric array
instance and pass that to a function, or call buffer() on the _data
member of a Numarray array instance.

The buffer() object has been changed in Python 2.4 (or was it even 2.3?)
so that it retrieves the memory block address from the original object
each time it is needed, instead of getting it once and then storing it
permanently.  So it should be even safe if the original object changes
its internal memory block.
