Re^3: What is $::| ?

It doesn't seem to be the same as $|.

How did you arrive at that conclusion?

Given that the vars in perlvar are package variables found in every package, they should be.

>perl -le"for (0,1,0) { $|=$_; print $|, ${'main::|'} }"
00
11
00

>perl -le"print \$| == \${'main::|'} ? 'same var' : 'diff var'"
same var

How did you arrive at that conclusion? I had simply tried `$ perl -e '$\|=1; print "$main::\|\n";' \|` [download] On second thought, it's obviously a parsing issue, i.e. `$main::\|` is not being parsed as `${'main::\|'}`, but rather as `$main::`, so the '\|' is being printed literally.

You can see form the trailing "`\|`" that you were referencing `$main::` and not `$main::\|`, so there's no ground for drawing conclusions about relation between `$main::\|` and `$\|`.	[reply] [d/l] [select]

Yeah, I got that in the meantime. Considering that the first version of your node Re^3: What is $::\| ? read "Like the OP said, it's not valid Perl. Are you asking me to speculate if `$\|` and `$main::\|` would be the same if `$main::\|` was valid? Probably. It is the case for `$_` " it appears that it did take even you a second thought to figure out that one needs to write `${'main::\|'}` :)	[reply] [d/l] [select]
