(PAIr Language)

A programming language in the genre of esolang by Chris Pressey, Cat's Eye Technologies, May 25, 2011

Pail is a programming language based on pairs; just as Lisp stands for LISt Processing, Pail stands for PAIr Language. Its original working title was "Bizaaro[sic]-Pixley", as it attempts to resemble Pixley while turning several concepts on their heads: use pairs instead of lists, quote by default instead of eval by default, and allow not just values but also names of bindings to be expressed.
