export fn name(...) is a C function by that name (numbers, bool, char, pointers in and out).
--shared builds lib<name>.so / <name>.dll with no main. finch_module_on_fatal(handler) lets the
host take runtime errors over (longjmp out) instead of the process exiting.
tests/shared.sh: a C host loads one, calls it and survives an index error.

- fn Struct.method(...) with self by reference, also on C structs
- map[K]V: insertion-ordered hash maps, literals, m[k] += 1, has/get/remove/keys/values
- -> T! / -> !, return error(...), or <value>, or { err }, try; fallible int/float/read_file/write_file/delete_file
- for i, x in list / for k, v in map
- print and str() share one text formatter
- LSP: method and map completion, method signatures; grammar and snippets for VS Code and Kate
- tests: 74 (methods, errors, maps + 11 failure cases); docs at all three levels, en and pl
