//! Source map, spans, diagnostics, lexer, AST and parser for Presk.
//!
//! Step 1 of the 0.1.0 plan (presk-specs/implementation/presk-plan-0.1.0.md).
//! The syntax accepted is the one of `presk-specs/examples/*.psk` and of the
//! specification chapter; where the two disagree or the grammar is only
//! sketched, the choice is recorded in `docs/spec-questions.md`.
