Comment (by jdemeyer):
Replying to [comment:8 tscrim]:
> In the same vein, I'm not sure an `ArithmeticError` is the proper type
of error as no arithmetic is being performed in contrast with
`cross_product`. I'm thinking this should actually be a `ValueError`
I would argue for `TypeError` actually. In Sage, `TypeError` is usually
given for objects from the wrong parent. For example
{{{
sage: vector([1,2]) + vector([1,2,3])
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
...
TypeError: unsupported operand parent(s) for '+': 'Ambient free module of
rank 2 over the principal ideal domain Integer Ring' and 'Ambient free
module of rank 3 over the principal ideal domain Integer Ring'
}}}
