simple ++ on maps

Thanks for this, @Nimrod007! Could you explain how you consider this a puzzler, i.e. how the language here is behaving in an unexpected way?

A puzzler should ideally have the reader thinking that they know what the result should be, but then the language behaves differently. In this case, if you understand how ++ works, the language seems to behave predictably.

i agree that if you know how ++ works the answer is predictable.

Thanks, @Nimrod007! I've opened a new PR #110 to hopefully make things clearer.
