So s[0] type would be a string with a size between 1 and 6 bytes. s[1].addr
would depend on the byte length of the first codepoint. s.len would not be the
length in bytes anymore. One would need a new "length" for that? Instead of
strings + cstring the FFI would need to use seq[char]? But besides that and
breaking everything. It would need to decode and encode (and check) utf8
everywhere. Reading and writing strings would not be anymore transparent and
needed everywhere to specify it's encodings. Does not sound like something I
want in a systems programming language as standard string type.
