ATLAS: A VOYAGE OF DISCOVERY ON THE HIGH SEAS OF SCRIPTING
summary
Atlas is a small scripting language implemented in Scala with a serializable AST and an interpreter generalized over any F using Cats/Scalaz patterns (Either, StateT, monad transformers) to handle async, errors and sandboxing. It supports closures by storing an environment with functions, exposes native functions to call Scala, and enforces execution limits via interpreter state. Prototype works but is immature and two to four orders of magnitude slower than equivalent Scala (about 10x slower than JVM JavaScript).
