            print(size(b)) // 4

Components

const edgeLengths = comp(e) { all : scope.sx }

const faceAreas   = comp(f) { all : geometry.area() }

Example --> print(edgeLengths)       // (4)[2,2,2,2]
            print(faceAreas)         // (1)[4]
            print(size(edgeLengths)) // 4
            print(size(faceAreas))   // 1
