That's confusing. I first thought maybe $| was a tied variable, which
would explain this behavior. So, I tried doing 'tied $|' to see what
it was tied to. The result was undef--meaning it's not a tied. But,
wait, 'tied %ENV' also returns undef. Does anyone know why? Is this
a bug? (All of this is in Perl 5.6.1 on Solaris.)
Anyway, I guess the larger moral of this story is that $| has a
Boolean value, and you should only think of it in terms of true
(nonzero) or false (zero), and not do math operations on it. Why
would you want to increment $|, anyway?
