Homoiconic C ("HC") is a minimalist and highly expressive alternative to traditional programming languages. It eschews traditional grammar, keywords, and reserved words, focusing instead on a single type of object called a Frame. HC's syntax is a thin veneer over its robust semantics, which are centered around ubiquitous scope, consistent evaluation, and homoiconicity (symmetry between code and data). This cheat sheet provides an overview of HC's key syntactical elements.
