At the risk of sounding unconstructively negative, I think this is a
misuse of attributes. For someone used to read standard Python code,
where attributes are, well, attributes, code using this notation is
just weird.

Personally, consistent notation is more important than short notation.
The Pythonesque solution to this problem, in my opinion, is separate
matrix and array objects (which can and should of course share
implementation code) plus explicit constructors to convert between the
two. I am a bit worried that kludges such as fake attributes set
bad precedents for the future.

One of the main reasons why I like Python is its clean syntax and its
simple object model. This kind of notation messes up both of them.

Konrad.
