I am not the best person to ask as I have a vested interest.
I find that mathematical notation is strongly context
sensitive which gets translated into types when done
as computational mathematics. Thus, I believe that a
mathematical language needs to be strongly typed.
Python is not strongly ty

I find it amusing that mathematicians are being told that

after all, a specialized language that took me years to

In any problem you wish to solve with a program there is always
an impedance mismatch (like hooking a soda straw to a
Dear all,
Students discover Sage for mathematical computations,
and the functions are the most usual way to write mathematics.
So I prefer a light interface with the matrix function "trace(...)".
The determinant is a function and a method... but trace is only a method.
And .methods() aren't ful

Actually, there is also a slight (but sometimes significant)

Something is not quite right in the cleverness used to output matrices:
sage: M
76 x 58 dense matrix over Integer Ring (type 'print M.str()' to see
all of the entries)
sage: M.hermite_form()
76 x 58 dense matrix over Integer Ring (type 'print
hnf-True-False.str()' to see all of the entries)

Hey Guys,
Sorry for the repost. I have already posted this some months ago
but it received no answer on sage-support. I am afraid this is a bug
but the guidelines ask to first post here before reporting something
on trac. Could you look into this (I have done the best to illustrate
the problem):
