Yes and no. autovivification in general applies in writish kinds of context, but that is a somewhat imprecise concept. Note that keys() can be in lvalue context (allowing you to set the hash bucket size); it just so happens that keys always puts a hash dereference argument in lvalue context whether or not keys itself is; perlglossary is quite correct in terms of the context applied to the dereference itself.
