This isn't a typical question to solve a specific problem, it's rather a brain exercise, but I wonder if anyone has a solution.
In development we often need to disable or switch some parts of code to check different approaches. To do this we use comments or
I'm not sure I should post this because it's not something I think is 'good code', but I'll admit to having used the following technique as a quick-n-dirty way to be able to quickly switch between two small snippets of code when I'm just checking something out:
// in the following , foo() is active: /**/ foo(); /*/ bar(); /**/
Now just remove one of the asterisks at the front:
// now bar() is active: /*/ foo(); /*/ bar(); /**/
Of course, this should never make it past the "just checking things out" phase...
