Yes, these were disallowed by the same patch that disallowed multi-arg
list.append.  Nobody mentioned index/etc because there were no known
instances of that in real code; multi-arg append unfortunately showed up in
some very early modules in the std distribution, and appeared to get copied
widely by people who listened harder to the compiler's silence than the
documentation's screams <wink>.
