I would recommend to follow one basic programming principle: explicit
is better than implicit, meaning being concrete and specific instead
of abstract and general ;-)
I think this is more explicit and _not_ expected to change:
<hansl>
matrix m = {}
</hansl>
Yes, in principle I agree. However, you can do "matrix m n o" on one
line to create several objects, and you would need three separate lines
being explicit. And I really like having less code lines, that's also
what attracted me to Python in the past.
thanks
