My preference would be for matrix multiplication with 1d
arrays to always raise an error. Anything else is too
As a second choice, having them always interpreted as
a specific kind of vector (either row or colum, as long as
its *always* the same) is equivalent to me.
But shouldn't there be a clear justification of such
implicit conversion? Is it really so useful?
