/**
* An attempt to show that even numbers are not immutable in go.
* This example is as parallel as I can make to a similar elixir program.
* The idea here is the makefun() function declares a new variable "a".
* Then creates a function.  Then change the value stored with a. And
* finally returns the function. If a was truly a variable, then
* when execute the returned function
* should print the changed value of a. If immutable, then the original value.
* This is not a perfect test, but it is the best I can think of.
