Hi Simon, You know the .new_matrix() method, as well? It does not currently make an "empty" matrix, but defaults to a zero matrix. The options (coerce, entries, copy) are not documented very well, and I can't say that reading the code has been real helpful either (for me).
I've tried to chase my way back through some of the low-level matrix creation code and frequently lose my way. It could benefit from some love and attention, I think. I've had it in the back of my mind for a while now. Maybe the following are related: #10158, #10312, #10628.
