The Reasoned Schemer by Daniel P. Friedman, William E. Byrd and Oleg Kiselyov is one of the "Little Lisper" books. It concentrates on a logic-functional extension to Scheme. Though the language is never given a name in the book, it is a minimal version of KANREN. miniKANREN is the Scheme-based implementation. cl-kanren-trs is our take.
cl-kanren-trs implements the language of The Reasoned Schemer with CLOS hooks to extend the types that can be the subject of unification. Each terminating form from main text is (or will be) implemented as part of the test suite.
More to come!
The test suite will eventually depend on Stefil.
