//! Hand the real Tk a stand-in interpreter and record what it asks for.
//!
//! Every line of output is one call Tk made through the stub table:
//!
//! ```text
//! tkslot <n> <table> <index> <name>   a call that was served
//! tktrap <n> <table> <index> <name>   the call that had no implementation
//! ```
//!
//! A `tktrap` line is followed by `abort`, so a run ends either at the first
//! unimplemented slot or when `Tk_Init` returns. Either way the preceding
//! `tkslot` lines are the ordered call sequence, which is the deliverable.
//!
//! Built only with `--features tk`.
