Comment 4 for bug 1854849

I reviewed libscalar-list-utils-perl 1:1.53-1 as checked into focal. This shouldn't be
considered a full audit but rather a quick gauge of maintainability.
The guts of this perl module is in ListUtil.xs which is turned into C code. I did run that
portion of the build through coverity, which did not complain about anything I found to be
concerning.

libscalar-list-utils-perl is a replacement for the default List::Util distribution that
is built into perl core and adds some additional subroutines.
