위키피디아 소개를 옮겨보면.. The PCASTL (an acronym for by Parent and Childset Accessible Syntax Tree Language) is an interpreted high-level programming language. It was created in 2008 by Philippe Choquette[1]. The PCASTL is designed to ease the writing of self-modifying code. The language has reserved words parent and childset to access the nodes of the syntax tree of the currently written code[2].
