In response to a question
I asked earlier today,
provided a very helpful answer
straight from the end of the perlvar man page.
However, I do make it a point to RTFM before I ask.
I had already looked over perlman:perlvar
and hadn't seen the section cianoz quoted.
It turns out that it's one of two sections
at the end of the perlvar man page
("Technical Note on the Syntax of Variable Names" and "BUGS"),
that simply aren't there in the on-line document.
(And they're not just missing from here, either; the
doc over at
is the same as the one here at perlmonks.)
My man pages are from 5.6.0,
and I don't find an identifying version number
in the on-lines copies,
so is this just a version difference?
