Unlambda

Unlambda is a programming language invented by David Madore. This language is the product of the intersection between two 'marginal' programming languages.

• Programming languages or esoteric programming language, of which the canonical representative is INTERCAL. This means that this language was designed to make programming difficult and suffering.
• Functional programming languages, of which the canonical representative is Scheme (a Lisp dialect). This means that the only object manipulated by language is function.
