We argue, though, that deeply buried within that 265- line miniKanren implementation is a small, beautiful, relational programming language seeking to get out. We believe µKanren is that language.

In this presentation we will discuss µKanren, a relational language in the family of miniKanren. We will discuss the basics of relational programming, variable binding, and the strategy that µKanren uses for backtracking. We will explore these concepts using elm-microkanren[2]. Finally, we will briefly cover the work needed to bring µKanren into feature parity with miniKanren using my own extensions to elm-microkanren (plus error handling and named variables.)
