So this doesn't do what you think it does.

Hi folks,
I am currently writing a code which uses a matrix in a
previously defined function written in the same sage window, but I
keep on getting this error message : TypeError: unable to coerce to an
integer.
thank you for your time.
Kind Regards

my code is this :

I have a proposal about M * A, where M is a Sage matrix and A a NumPy
array. The current behaviour appears to be the Kronecker product; I'm
guessing that this is just be a side-effect of Python applying
element-wise __mul__ (if it is intentional and relied upon, this
proposal got harder).

Hello,
the following issue is related to #519: malb created deallocation
routines for the random state used by the Mersenne Twister in the gmp.
We used to have many states leaked (about 40 in a usual session), but
that has been fixed. To my surprise we still leak one state:
==32085== 2,500 bytes
