Wrong result for scalar-vector product

[tkoolen]

julia> using DynamicPolynomials

julia> @polyvar x
(x,)

julia> y = x * [x, x]
(PolyVar{true}[x, x])x

julia> typeof(y)
Term{true,Array{PolyVar{true},1}}

This calls

MultivariatePolynomials.jl/src/operators.jl

Line 27 in 518eda6

@eval Base.$op(p::APL, α) = $fun(p, α)

.

This is related to #103 and due to the design that what isn't a polynomial is a constant to avoid restricting constants to, say, Number so that constants can for example be matrices of Float64 (we also never assume that * is commutative for this reason).
We should maybe make a special case for AbstractArray or polynomials and fallback to broadcast for operation such as scalar * array, array * scalar and array / scalar. Do you see any other ones ?

Fixed in #105.

Sorry for not responding to your earlier comment @blegat. Thanks @saschatimme!
