I suspect that many of these issues would be resolved by using Maxima
directly, using
one of the graphical interfaces (e.g. wxmaxima).

Well, there is a general trend towards using functions instead of
attributes in Sage. I think the main reason is for documentation (I
wish python had attribute docstrings that we could query!).
They wouldn't be attributes

Maurizio's function is pretty nice! It's exactly what I was looking
for. I think it should be included in future releases. But it's a bit
slow (at least for the 1..1e9 range), maybe it should be rewritten or
compiled.
The only thing I didn't like is that it saves the image to the current

If the [...]m syntax is messing too much with Python's syntax, don't
implement it then, but I keep thinking there should be an easier way
than the one right now to input matrices. It's just not comfortable
for people who does an intensive usage of matrices.

There is no policy. My personal policy is that I'm always

Ok, I didn't think about the problems that using real numbers where

better forget about this one.

Good to know that Sage already supports units, when were they
implemented? Apparently not in 4.1.2
