What I describe is not list notation. Specifically, the glob {1,2,11}

1 2 11
$ echo {1..11}
1 2 3 4 5 6 7 8 9 10 11
If we want to avoid confusion, then we should not use AND notation
in places where OR operation is intended.
I'd also suggest the shell brace expansion like syntax. The AND or
OR ist what an application makes out of the syntax, not what the
syntax originally is for. Infact, it just describes a set. For your
needs, it would describe a "set of octetts".
I would second this opinion, too.
{1,2,4..8..2}
--> 1,2,4,6,8
Is this the step syntax? That's IMHO pushing it too far...
