I'm personally not really partial to any side of this discussion,
given how I don't use matrices at all (I'm content with a simple
mental model of arrays, and use dot() as necessary). But it's
probably worth mentioning, as a data point, that the python language
has a well established precedent for 'iteration over a FOO where a FOO
is yielded':
In [1]: s='abc'
In [2]: type(s)
Out[2]: <type 'str'>
In [3]: map(type,s)
Out[3]: [<type 'str'>, <type 'str'>, <type 'str'>]
I know strings aren't matrices, so take this as you will in terms of
being plus, neutral or minus regarding your discussion. I'm just
offering the data, not interpreting it :)
Cheers,
