Note that |
exists in %::
:
perl -WE '$| = 1; print ${"::|"}'
1
but you have to use ${
to get at it.
It's possible that forcing $::|
to be magic came about via the $::|=1;
example in 04_tinderbox.code mentioned above, since PPI at the time did not recognizing the |=
operator.
It's totally possible it was an oversight.
If is in the tinderbox test then it does match a real character sequence found in the wild. Might well have been a case of mistaken identity.

PPI::Token::Magic and the Changes file explicitly make "$::|" a magic variable, but I haven't found a version of perl that will compile it:
Making it magic was committed 2005-01-17, but there's no subversion/GitHub history back that far.
t/data/08_regression/04_tinderbox.code
tests that%::
is non-magic, but also wants$::|=1;
to be magic.Should %:: (and $::...) be magic or not? Is there any cause for '$::|' to be treated specially in Magic.pm?
