Facilis is a strongly typed functional language that aims to be low level. Facilis uses a hand-written recursive descent parser made with love.

Factorial Example

impure foreign putchar(c of u8) -> void
impure foreign tostr(num of void*) -> string

impure write(str of string, start of i32) -> void {
	putchar(str[start])

	if start != str.length() {
		write(str, start + 1)
	}
}

pure fact(i of i32) -> i32 {
	if i == 1 {
		return i
	}

	return i * fact(i - 1)
}

impure main() -> i32 {
    write(tostr(fact(6)), 0)
}

@DynamicSquid We actually accept command line arguments, we just passed "out.cpp" as the output file, but yeah, we used a bit of Bash, we could've changed it to pure C++, but it's not easy to query the system and execute other code in a portable simple fashion. In a way we just took the easy way out, also, you can hand tune the output or check it for bugs yourself, since our implementation is still pretty buggy.
