+* We do not use `nimpretty` - as of writing (Nim 2.0), it is not stable enough for daily use:
     * Can break working code
     * Naive formatting algorithm
 * We do not make use of Nim's "flexible" identifier names - all uses of an identifier should match the declaration in capitalization and underscores
