One thing I've run into with Lua 5.3-work1 is that I want to make code

"//" operator.

I share Miles' concern here. This is the first serious break with Lua 5.1 after more than eight years - like a Python 3 moment. I understand that people sometimes need 64-bit integer arithmetic (which is why his proposed idiv won't in general work) but it's a very specific point to choose to break with the past.
