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 package handed over its .c files and its `link` arguments the moment it was
imported, whatever the importing program did with it. That is what made sand's
two halves two files: anything naming vendor:raylib linked libraylib on every
target, and on wasm32 that link cannot succeed, so the headless run could not
so much as mention the package the interactive one needs.
Reach.link answers it from the checked program instead. Start at main and at
the globals that run before it, follow every call — including the Handled
frames, where a lifted handler clause is reached by address and by nothing
else — and keep what is reached. A package none of whose externs survive
contributes no C and no linker argument.
Dropping the flags alone would only move the failure: the bodies that called
into raylib would still be emitted, and wasm-ld would fail on the symbols
rather than on the argument. So the same walk prunes the functions and externs
too. Only those — globals, structs and unions stay, because an unreferenced
global is bytes in BSS and a dropped one is a silently different program.
Dev builds keep everything. What a REPL may redefine next is not a function of
what has been called so far.
