Comment #4 on issue 1838 by smichr: Add support for [0]*S(5), etc.
http://code.google.com/p/sympy/issues/detail?id=1838
In objection to my comment, we could reserve one of the sides (preferrably
right) for
the normal scalar behavior of python so [0]*S(2) would give [0, 0] and if
someone
wanted to do vector multiplication that could be done on the left for a
scalar or on
the left or right for a non-commutative symbolic entity (which won't be a
scalar).
[1, 2]*S(2) => [1, 2, 1, 2]
S(2)*[1, 2] => [2, 4]
x=Symbol('x', commutative=False)
var('a b')
x*[a, b] => [x*a, x*b]
[a, b]*x => [a*x, b*x]
