in thread Redefining Imported Subs: of scope and no
Hit the reply link, the reply link, the link that says reply to reply to the post you want to reply to , that is the link you're supposed to click to have threaded discussion, otherwise it is not theaded discussion but a flat list, flat lists are not effective for following a conversation, that is why the twitts and other "chats" use the @username stuff, so click the reply link and its like this isn't some chat and not flat at all...
As to your question, CORE is CORE::, many threads about CORE::, ex::override
perl -e " CORE::say 1 ; "
perl -e " CORE::say 1 ; say 2 "
perl -E " CORE::say 1 ; say 2 "
