Patch 11038 added support for $^N, but the description in perlvar did
not include a mnemonic. (Possibly because caret variables are getting
so scarce that nowadays they tend to get picked by availability, not
because the letter stands for anything in particular, at least not
without some stretch of the imagination.) Still, here's a suggestion
for a mnemonic. This is open for discussion, as it's only something I
thought of and may not fit. Feel free not to apply it (for example, if
you think the explanation is bad, badly worded, or not necessary).
