Hi Ken

Thanks for pointing to the bug, that's indeed an ugly case ...

> however, https://perldoc.perl.org/5.34.1/List::Util has "Since version 1.29." for both pairgrep and pairmap.

That's the modules version, 5.20.0 comes bundled with 1.38 (look at upper right corner)

> I now note that https://perldoc.perl.org/5.34.1/List::Util#KNOWN-BUGS lists "RT #95409" while https://perldoc.perl.org/5.20.0/List::Util#KNOWN-BUGS does not.

5.34.1 comes bundled with v1.55 of List::Util ... I assume the bug was discovered and included later.
