summary

Describes XL, a minimalist homoiconic programming language with eight node types and a single operator for parse-tree rewrites, and examines hard problems that arise when trying to keep a language both simple and expressive. Uses five concrete example areas—numbers/expressions/statements, non-object primitives like min/max, containers (lists/arrays), text I/O/formatting, and complex numbers—to contrast limitations and subtle bugs in mainstream languages with XL’s concept-programming–guided solutions and code-generation choices.
