I think that it would be better to pick the other meaning of C<^4> instead,
meaning C<0..3>, because that keeps the meaning of "^" consistent as "up to but
not including". Then also saying ^4 means you get a range of 4 elements, so
there is that consistency too.
Also, the code example still reflects the 0..3 meaning that I prefer, so it is
an error if the meaning you picked is chosen.
