While I was working with cases I tried using underscores in my patterns as byte separators, expecting it to match the integer literal syntax, but it was rejected.

I'd like to be able to write patterns like "0001_0---"—does this seem like a good idea, or is the potential confusion between - and _ a problem?

I think the potential confusion is a problem. Since we don't need it to be a single lexical token (like Python does), what about just using spaces?

I would also be happy with spaces as the separator.
