@stiabhang How does it not also match the second, but with a different value and remaining input?
EBNF ---- how is this [abc]* - ([abc]* 'xyz' [abc]*) different to this: [abc]* - ([abc]* 'xyz') ?

@stiabhang Also, I think you misplaced a hyphen.

@stiabhang imo, "abc" matches both. None of these match: aaaxyz aaaxyzaaa aaaxyzxyz What string matches one and not the other?

@stiabhang I believe the hyphen denotes subtraction of the subsequent grammar, eliminating its possibility.
