> This sounds great! What about matrices?
If a dense matrix is good enough for you then you can just convert it to a
List of Lists in Gap and then use the `.sage()` method which recurses
through the lists and can convert numbers:
{{{
sage: from sage.libs.gap.libgap import libgap
sage: M = libgap('BlockMatrix([[1,1,[[1, 2],[ 3, 4]]],
[1,2,[[9,10],[11,12]]], [2,2,[[5, 6],[ 7, 8]]]],2,2)')
sage: M
<block matrix of dimensions (2*2)x(2*2)>
sage: M.List().sage()
[[1, 2, 9, 10], [3, 4, 11, 12], [0, 0, 5, 6], [0, 0, 7, 8]]
sage: matrix(ZZ,_)
[ 1 2 9 10]
[ 3 4 11 12]
[ 0 0 5 6]
[ 0 0 7 8]
}}}
