It is well known that the ruby comments are used to leave notes or micro-docs within the code and is ignored by the Ruby Interpreter. But can we do other things with comments?

A lot of times when jumping across branches on your Git repository, you’ll come across situations where you need to un-stash a single file from your stashes.
