I'm not sure it does...  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.
