- finch.toml: name, entry, paths, include, links, libdirs, cflags, ldflags, and [target.windows] etc.;
finch run / build / test with no file use its entry
- import thread: spawn, join, mutex, cpus; atomic_add/sub/load/store/swap/cas built in
- finch fmt [--check]: indentation by { }, trailing spaces, empty lines; also as LSP formatting
- link "x.cpp" (or in finch.toml): built with the C++ compiler, which then links (FINCH_CXX)
- #define RAYWHITE (Color){ 245, 245, 245, 255 } imports as a Color
- push(body) where push takes ptr[Body]: the same as push(addr(body))
- --target android (NDK clang from ANDROID_NDK_HOME, -llog)

- "x is \(x)", "\(speed, 2)" (two digits after the point), also in """ text
- test "name" { ... } blocks; assert(cond) and assert(cond, why); finch test runs each on its own
- the program's object and its C files (link "x.c") are kept in the cache until they or their headers change
- runtime errors show the calls that led there (finch run, finch test, -g, -O0, --trace)

- const NAME = value (numbers, text, other constants; typed: const f32 G = 9.8), also module.NAME
- x := if c { a } else { b }
- """ ... """: the closing quotes' indentation goes from every line
- min, max, abs, clamp for any numbers, unless your own function has the name
- import ui/button (a module in a folder), import path as p
- fs: read_bytes, write_bytes, exists, is_dir, mkdir (with parents), list, remove_dir, data_dir(app)

Also frees main's args and the message of a failing main (valgrind was not clean on two tests).

src/embedded.fch (made by tools/pack.fch, checked by tests/run.sh) holds runtime/finch_rt.c and std/; when they aren't
beside the binary they're written to the cache folder once. All the sh/cmd specifics of the driver (quoting, temp dir,
mkdir, rm, mv, null device, path separator, cache dir, binary stdio) moved into host.fch / host_windows.fch.
