A small (toy) Reverse Polish Notation implementation. The core code is less than 100 lines long.

polish uses float64 numbers throughout.

An example command-line program lives in the calc directory. Once compiled, it can be run like:

calc 1 2 + 4 \* 3 /

Being that this is a toy/teaching implementation, polish is subject to change; if polish ever stabilizes enough for production use, it will be found at <github.com/xtgo/polish>.
