print-str, print-i64, print-f64, print-bytes, print-line and newline leave the prelude. print and println are the whole printing surface now, and print is the better call at every one of the sites that used them: it is the same structural walk without the newline, so the no-newline case the family was kept for is covered, and it takes the value as it is. The old print-i64 forced an explicit (i64 x) at every call site, because this language widens nothing implicitly; that cast is gone from 127 places. Dropping it moves one answer. hash-grid returns u64, and the cast through the signed printer showed sand-headless's hash as -2851001042534928384. print routes a u64 through flan_u64_to_bytes, so it now prints 15595743031174623232 — the same 64 bits, read as the unsigned number they are. The pinned expectation follows the correction. test-flan-dev.el and test_session.ml both reached for print-line as "a name the prelude has"; they reach for rand-seed instead.

;;;; A program that stops, for driving the break loop from an editor.

;;;;
|
|
;;;; It errors on its first frame, with nothing having handled the condition,
|
|
;;;; so [flan dev] meets a program that is already stopped — which is the state
|
|
;;;; an editor has to cope with, and the one that is hardest to arrange on
|
|
;;;; purpose later. Two restarts are on offer and they return different values,
|
|
;;;; so the transcript says which one was chosen.
|
|
;;;;
|
|
;;;; After resuming it keeps polling, because the claim worth testing is that
|
|
;;;; everything else still works on either side of a break.
