Some parts of List::Util are a little ill-conceived. For example, the existence of separate min and minstr functions (and max/maxstr).

Two points:

  1. All of List::Utils function except shuffle, can be reproduce using reduce alone.

    Adding uniq() would be nice if it ran more quickly than a pure perl implementation: sub uniq{ my %h; undef @h{ @_ }; keys %h }

  2. The need for min/minstr is forced by being non-core.

    min amd minstr run more quickly than their equivalents using reduce, because they avoid the need to callback to Perl for every item.

    Sort gets away with using a callback by recognising the simple patterns of callback block {$a<=>$b} & {$a cmp $b} and bypassing them in favour of dedicate opcodes for those simple cases.

    Effectively, sort{$a <=> $b } is the subroutine name. sortn would be shorter, easier to type and remember. Ditto for sorts

    List::Util doesn't have that option because it is outside the core.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
