I looked through perlop and grepped all the pod for 'interpo' and 'concat' on the same or adjacent lines, but didn't find that. Anyway, why shouldn't it say that in the warning message as well? If we want to educate people that string interpolation is the same as concatenation, that seems like a good place to do it. Ronald
