Lazy rank one matrix

[blegat]

Trying to build a lazy rank one matrix, I get an error

julia> x = ones(2)
2-element Vector{Float64}:
 1.0
 1.0

julia> a = @~ x * x'
Applied(*,[1.0, 1.0],[1.0 1.0])

julia> materialize(a)
ERROR: AssertionError: length(x) == 1

This however works:

julia> a = @~ x .* x'
Base.Broadcast.Broadcasted{Base.Broadcast.DefaultArrayStyle{2}}(*, ([1.0, 1.0], [1.0 1.0]))

julia> materialize(a)
2×2 Matrix{Float64}:
 1.0  1.0
 1.0  1.0

I normally just do ApplyArray(*, x’, x)
