- struct with default values; constructors Point(1, 2) / Point(x: 1); field access, auto-deref through pointers - []T arrays with bounds checks, literals, for-each, push/pop/insert/remove/clear/resize/find/contains/join/slice/reverse/sort - str carries its length: .len, s[i], +, comparison, sub/find/split/trim/upper/lower/replace/repeat/bytes, str(x), int(s), float(s) - Memory: values own their memory and are freed at the end of their block; assignment copies, temporaries move; parameters are lent and only copied when the function changes them; defer; new()/free() for manual heap memory - input(), read_file/write_file/file_exists, exit(), fn main([]str args) - Finch modules: import name, module.fn(), module.Struct - C structs from headers (fields, fixed arrays, nested); passed and returned by value with the System V x86-64 ABI; addr(fn) gives C a callback - link "file.c" compiles and links your own C code - -g emits DWARF debug info (gdb/lldb) - Small C runtime (runtime/finch_rt.c) embedded in the compiler, cached in ~/.cache/finch - Tests: 58, all clean under valgrind (MEMCHECK=1 tests/run.sh) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
