Although it returns a NotImplementedError when the coercion is not defined, which is the wrong kind of error, but at least it is an error. I'll see if I can fix this.

I found this funny: 

sage -t free_module.py
    [666 tests, 1.09 s]

  • Ticket #15305 – Description

    initial v14  
    11Given modules `A1, A2, B1, B2` with coercions `A1 -> B1` and `A2 -> B2`, there is the natural coercion `A1 # A2 -> B1 # B2` as the tensor of the factor coercions. This ticket implements the above coercion as a natural coercion for `CombinatorialFreeModule_Tensor`.
