So List::Util is in there on my platform right enough

Aaah ... cool.
AFAICS, this absurd dependency is not present in perl-5.36.0 - on both Windows and freebsd-12.0.
On Windows (perl-5.36.0), your script outputs: 
Loading File/Copy.pm
Loading builtin.pm
Loading overload.pm
Loading overloading.pm
Loading warnings/register.pm
Loading File/Spec.pm
Loading File/Spec/Win32.pm
Loading Cwd.pm
Loading Exporter.pm
Loading XSLoader.pm
Loading File/Spec/Unix.pm
Loading constant.pm
Loading Config.pm
Loading Time/HiRes.pm
Loading Carp.pm

[download]
On freebsd (5.36.0), it's exactly the same - except that Carp.pm and File/Spec/Win32.pm are not loaded, and Exporter/Heavy.pm is loaded.

I'm sure there's a module for this but I can neither remember nor find it just now

I reckon the code you posted is much clearer for not having loaded that module (whatever it is ;-)

Cheers,
Rob
