  It is a simple interpreter for expressions. See more at : https://en.wikipedia.org/wiki/Shunting-yard_algorithm https://en.wikipedia.org/wiki/Shunting-yard_algorithm

    These toy-intepreters are very useful for putting scripting support in your applications. I recently wrote something similar for allowing evaluation to be applied to arbitrary golang objects/structures - so that I could write simple scripts rather than hard-coding logic in my application. With only a few primitives it becomes very useful! https://github.com/skx/evalfilter https://github.com/skx/evalfilter
