No but I'd often wondered why the combined brains of the world could not

I'm sure there were many such designs proposed back when tomorrows World

When I was young my gran had an electric iron that had a BC male connector
on it to plug into a lamp socket. so we have come a long way since then, or
have we?

I recently bought a batten lampholder that has shielded BC contacts.
