The Concatative Language XY
Summary
The Concatative Language XY is described as a direct descendant of the K and Joy paradigms, using a stack (X) and a queue (Y) to drive evaluation. It defines a comprehensive set of operators, forms (dyads and monads), pattern notation, and a language structure that emphasizes continuation-passing evaluation and non-flat semantics, with discussions of XY 2.0 and script support.
