type Arr<t> {
  _data: t[],
  _len: U32
};

// when t is at most 8 bytes wide, inline parts of arr
type Arr<t: Sized<(_<=8)>> {
  _inline: t[4],
  _heap: t[],
  _len: U32
}

// bit array
type Arr<Bool> {
  _data: U8[],
  _bits_len: U32
};

It is not "easy" to implement, but I don't think it would be "hard" either.
