Re^4: What is $::| ?

How did you arrive at that conclusion?

I had simply tried

$ perl -e '$|=1; print "$main::|\n";'

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]
