Abstract
We present a miniKanren-based type inferencer for an educational programming
language with first-class functions, S-expressions, and pattern-matching. The
language itself is untyped which adds a certain specificity to the problem and
requires the employment of techniques conventionally used in implicit/gradual
typing settings. The presence of polymorphic and recursive types poses a
certain challenge when implementing the inferencer in miniKanren and requires a
number of tricks, optimizations, and extensions to be used; we report on those
as well.
