Turns the ASCII capitals of s into lower case, in place. Other bytes are left as they are, so UTF-8
text is not folded. s must be writable, not a string literal.
to_lower_in_place :: (s: string)
Parameters
- s: string
text := copy_string("MiXeD");
defer free(text);
to_lower_in_place(text);
assert(text == "mixed");
