Fexl - a Function Expression Language

Fexl is a simple but powerful functional scripting language. It allows you to manipulate numbers, strings, streams, and functions easily and reliably, all within a secure "sandbox". (Fexl is pronounced fex'-uhl, similar to "pixel".)

You may browse or download the Fexl source code at github.com. (Updated Fri 2019-06-07)
