 This project provides an implementation of the efficient scope-safe representation
 for syntax with binders (think λ-abstraction, let-binding, for-loop, etc.).
 The underlying representation is based on the IFL 2022 paper by Maclaurin, Radul, and Paszke [«The Foil: Capture-Avoiding Substitution With No Sharp Edges»](https://doi.org/10.1145/3587216.3587224)[^1]. This project extends the foil with patterns, as well as two
