// This example shows how Go executes deferred statements in relation to a return
//
// This will output:
// 
// Setting string to  My first program says:
// Setting string to  3. Hello
//Setting string to  2. world
// Setting string to  1. from Deferred Go
// In main(), deferred() returned 3. Hello
// but str is now  1. from Deferred Go
