Subject: | Too low version of required List::Util |
The documentation describes a family of pair* subs, which are new to List::Util 1.2x. However, the runtime requirement for List::AllUtils is only 1.1 of L::U.
This results in error when trying to call or import pair* functions with (correctly installed) L::U 1.1.
It should be either noted in the documentation that newer version of L::U is required, or the required version should be bumped to 1.29.
