Testing the global object:
globalFixedFunction1: original
globalFixedFunction2: original
globalFixedFunction1: original
globalFixedFunction2: original
globalFixedFunction1: overwritten
globalFixedFunction2: overwritten

Testing object literal:
x + y = 1 (original)
x - y = -1 (original)
x + y = 1 (original)
x - y = -1 (original)
x + y = 1 (overwritten)
x - y = -1 (original)

Testing Object.defineProperty with accessors:
x = 0 (original)
x = 0 (original)
x = 1 (overwritten)

Testing the Math object:
Math.sin(Math.PI) = 1.2246467991473532e-16
Math.identity(Math.PI) = 3.141592653589793
Math.sin(Math.PI) = 1.2246467991473532e-16
Math.identity(Math.PI) = 3.141592653589793
Math.sin(Math.PI) = 1.2246467991473532e-16
Math.identity(Math.PI) = -3.141592653589793
Math.sin(Math.PI) = -3.141592653589793
Math.identity(Math.PI) = -3.141592653589793

Testing the Object constructor:
Object.identity(o) = [object Object]
Object.isSealed(o) = true
Object.identity(o) = [object Object]
Object.isSealed(o) = true
Object.identity(o) = I don't know you anymore...
Object.isSealed(o) = true
Object.identity(o) = I don't know you anymore...
Object.isSealed(o) = false
Object.identity(o) = I don't know you anymore...
Object.isSealed(o) = With the magic of JavaScript I pronounce you sealed!
