Likewise. Thought it'd be pronounced "slang", and thought the semantics would be you define LANG=<name of a language> at the top of the file (like a hashbang) and then write in whatever language you please. $LANG is a neato language because it has all the coolest features rolled into one unified design: polymorphic lifetime borrowing, endofunctor monoid monads, (stacked) coroutines, and even quantum data types.
