This is exactly what Raku does. Neither strings nor arrays have a `.length` method because it's arbitrary.

    [0] > "\c[FACE PALM]".chars
    1
    [1] > "\c[FACE PALM]".codes
    1
    [2] > "\c[FACE PALM]".encode.bytes
    4
    [3] > "\c[FACE PALM]".encode
    utf8:0x<F0 9F A4 A6>
    [4] > "\c[FACE PALM]".encode('utf-16')
    utf16:0x<D83E DD26>

FWIW, to get the "length" of an array, the method is `.elems`.
