xs is a minimal stack-based language with an array model and built-in functions that resemble Q. Unlike most stack-based languages, xs is evaluated from right to left, and to provide more Q-like syntax, it also allows "operators" that take one argument on the left. Functions are defined with parentheses, allowing nesting, and are dynamically scoped. Like Q, it has separate integer and float types, as well as a symbol type distinct from strings. However, it has no dict type.
