//! Implementation of incremental re-parsing.
//!
//! We use two simple strategies for this:
//! - if the edit modifies only a single token (like changing an identifier's
//! letter), we replace only this token.
//! - otherwise, we search for the nearest `{}` block which contains the edit
//! and try to parse only this block.
