Robert's patch on trac #1900 affords an opportunity to bring up a small simplification of adjacency_matrix(). It seems that the over_integers parameter over-complicates the interface. There are other more standard ways of specifying the ring over which you would like a matrix, like:
sage: # G is the graph sage: matrix(GF(2),G) or sage: G.am().change_ring(GF(2)) Can we get rid of the over_integers parameter in favor of these two ways of requesting a matrix over a specific ring? No functionality is lost (since the GF(2) matrix was only returned if there were no multiple edges). Simplicity seems to be gained, since, at least as far as I'm aware, adjacency matrices are usually thought to be over the integers, not over GF(2), even though we understand they are zero-one matrices. Of course, if I'm mistaken, let me know.
