2 questions about the patch:
* Why is this function named block_sum? What are we summing?
* Why are we limited to 4 arguments? Ideally, I would love to pass a
list to this function and
I agree with Didier's comments.
Judging from emails to the GAP support list
(Which also has such a function), a block matrix function will be
frequently used.
I think it should be well-documented.

These sound like good suggestions, I'll re-implement the richer
functionality.

Quick question -- why does this even have to be another function? Couldn't
we just expand the functionality of the matrix command, at least in

That may be true, but this function is already so overloaded that
understanding the code is very difficult.
well, what if there are both functions and matrix just calls
block_matrix if there are matrix objects in the list of

That's right. I should make myself more clearer next time.

Not just the block_sum, augment and stack functions.
As an example, let A, B, C, D be matrices and i want to construct a
matrix like E=[[A,B],[C,D]]

Sage's MatrixSpace and matrix don't have support for this.
numpy (which you get via import numpy) might have support
for numerical matrices like this.
CVXOPT also has support for this:

And, just to be clear,
It was my impression that he didn't want a matrix with matrix entries,
but instead wanted the matrix whose entries were given by the entries
of the submatrices.

That will be really easy to implement, I'll do it right now.
