If it's not a magic variable, the question is more, what is this global

I understand the difference, thanks. :-)
My point stands: how often have you used it in production code, apart from
the pattern of local $/, which I don't like for other reasons (mainly
inefficiency on reads)? And, of course, if you are using it, hopefully it's
tightly coupled to a very reusable module rather than scattered all over the
