At the same time the expect operator is not part of https://bford.info/pub/lang/peg.pdf. I think we should consider choosing another name for the expect operator, do you have a suggestion Ekaitz? I was considering "reusing" the she-bang, i.e. #!, since the expect operator throws an exception, but Janneke pointed out that ! as a modifier on the # comment is not very intuitive and I tend to agree.
