Thanks for this example! I realized that to modify a variable I have to add a "var" function to return pointer of an object, then I can use a "set" function to modify it. And in the beginning I also provided "get" function to return the value referenced by the pointer, however later I suddenly found that I don't need to do that, go template will automatically return the object itself, rather than the pointer. So this is my version https://play.golang.org/p/C1MtTKvdmGT I think it is more concise and elegant than the original example :-) Thanks so much for inspiring me!
