Is there any reason why a trailing comma is not allowed in an ArrayBindingPattern when it has a BindingRestElement? I noticed yesterday that my parser was erroneously allowing these, but the inconsistency with both ArrayLiterals and ObjectBindingPatterns is bothering me. Is this simply a mistake in the grammar? I understand that we wouldn't want to allow holes or other BindingElements to follow the BindingRestElement, but I don't see a problem with a single trailing comma.
