### Enumerate all solutions to linear system over finite field

Assume I have a matrix $A$ and a vector $b$, both over some finite field $\mathrm{GF}(q)$. I would like to enumerate _all_ solutions to $A x = b$ (there are only finitely many).

I can generate a particular solution using ~~$A ~~`A `

`\ `~~b$, ~~b

and I can generate the nullspace of $A$ using ~~$A.right_kernel()$, ~~`A.right_kernel()`

, but how should I combine the two to enumerate all solutions?
