//! declass: ES classes become prototype form, one algo step per file.
//!
//! The steps follow declass_algo.txt:
//!
//!   step_1  rewrite how a class is built (per function).
//!   step_2  splice the field initialiser into the constructor.
//!   step_3  fix the constructor header: rename, drop the capture (to come).
