	1	+### Data Structure Style
	2	+
	3	+ type Square struct {
	4	+ length float
	5	+ }
	6	+
	7	+ type Circle struct {
	8	+ radius float
	9	+ }
	10	+
	11	+ func Area(g GeometricObject) float {
	12	+ switch type(g):
	13	+ case Square:
	14	+ return g.length * g.length
	15	+ case Circle:
	16	+ return PI * g.radius * g.radius
	17	+ }
	18	+
	19	+ func Circumference(g GeometricObject) float {
	20	+ switch type(g):
	21	+ case Square:
	22	+ return 4 * g.length
	23	+ case Circle:
	24	+ return 2 * PI * g.radius
	25	+ }
	26	+
	27	+#### Object-Oriented Style

	37	+ return this.length * this.length
	38	+ }
	39	+
	40	+ func Circumference() float {
	41	+ return 4 * this.length
	42	+ }
	43	+ }
	44	+

	46	+ radius float
	47	+
	48	+ constructor(radius float) {
