in thread What is $::| ?

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 $|.

    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::|'}  :)
