Hmmm, without the parens, you get (because to-by is a tertiary
operator and it's left associative) the association as if the
parens were:
(0 to 15 by 2) to 5
which evaluates as:
0 to 5: 1 2 3 4 5
2 to 5: 2 3 4 5
4 to 5: 4 5
6 to 5: fail
8 to 5: fail
...
14 to 5: fail
which matches the output shown above. While it's not really obvious
it is consistent.
