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::|'} :)
