I want to make a dot product like

Eq6 := (sum(delta[i].v[i], i = 1 .. 3)).(sum(delta[j].w[j], j = 1 .. 3))

and get the complete result like

Eq7 := v[1].w[1]+v[2].w[2]+v[3].w[3]

but instead I get

Eq6 := ((Vector(3, {(1) = 1, (2) = 0, (3) = 0})).v[1]+(Vector(3, {(1) = 0, (2) = 1, (3) = 0})).v[2]+(Vector(3, {(1) = 0, (2) = 0, (3) = 1})).v[3]).((Vector(3, {(1) = 1, (2) = 0, (3) = 0})).w[1]+(Vector(3, {(1) = 0, (2) = 1, (3) = 0})).w[2]+(Vector(3, {(1) = 0, (2) = 0, (3) = 1})).w[3])

Is there a way to force the dot product operation all the way?
