Not always, at least for me, with which version did you check?

lanx@nc10-ubuntu:~$ perl -e 'CORE::say("bla")' CORE::say is not a keyword at -e line 1. lanx@nc10-ubuntu:~$ perl -E 'CORE::say("bla")' bla lanx@nc10-ubuntu:~$ perl -version This is perl, v5.10.0 built for i486-linux-gnu-thread-multi

As a minor nitpick, according to the definitions in perlglossary I'd rather use built-in and not operator to describe say, though the differences are indeed fuzzy.

    It apparently went missing until 5.16.

    Builtin functions are a slight superset of what both perlop and perlfunc call list operators and named unary operators. say is a builtin because say is a list operator. (It's fuzzy which builtins aren't operators.)
