Pixley is a very small subset of R5RS Scheme (or, if you prefer, R4RS Scheme), supporting only four datatypes (boolean, cons cell, function, and symbol) and only a dozen built-in symbols. The reference implementation of Pixley is written in 124 lines of Pixley (or, if you prefer, 124 lines of Scheme; and if you prefer more Scheme-ly metrics, it consists of 413 instances of 54 unique symbols in 684 cons cells.)
