Implement Utils Functions

[pdl]

Look at

• http://search.cpan.org/~pevans/Scalar-List-Utils-1.25/lib/List/Util.pm
• http://search.cpan.org/~adamk/List-MoreUtils-0.33/lib/List/MoreUtils.pm
• http://search.cpan.org/~pevans/Scalar-List-Utils-1.25/lib/Scalar/Util.pm

And see if there are useful functions which can be added to Test::Proto

[pdl]

List::Util

• first YES
• max/maxstr/min/minstr YES with cNum etc
• reduce => reduce
• shuffle => no
• sum => use reduce

List::MoreUtils

• any => see first
• all => grep suffices?
• none => grep suffices?
• notall => grep suffices?
• true => grep suffices?
• false => grep suffices?
• firstidx/first_index/lastidx/last_index => enumerate+first/last suffices?
• insert_after/insert_after_string => no
• apply => map
• indexes => enumerate+grep suffices?
• after => YES. also implement validate_many for this
• after_incl => YES. also implement validate_many for this
• before => YES. also implement validate_many for this
• before_incl => YES. also implement validate_many for this
• firstval/first_value/lastval/last_value => List::Util::first etc
• each_array => NO. Multiple inputs not supported
• each_arrayref => NO. Multiple inputs not supported
• pairwise => NO. Multiple inputs not supported
• natatime => contains_only or begins_with can do this, I think
• mesh/zip => NO. Multiple inputs not supported
• uniq/distinct => YES
• minmax => NO
• part => YES but low priority

Scalar::Util

Will probably require use Scalar::Util to be in force.

• blessed => p->blessed
• dualvar => NO
• isweak => YES I guess
• readonly => YES I guess
• refaddr => YES I guess
• reftype => YES
• tainted => YES
• weaken => no
• isvstring => YES do p->is_version
• looks_like_number => YES
• set_prototype => NO

[pdl]

Some of these can come later in the polished release.

List::MoreUtils

• any => array_any
• all => array_all, grep
• none => array_none, grep
• notall => array_any, grep
• true => array_all
• false => array_all
• firstidx/first_index/lastidx/last_index => indexes_of, or enumerate+first/last suffices?
• apply => map
• indexes => enumerate+grep suffices?
• after => array_after
• after_incl => array_after_inclusive
• before => array_before
• before_incl => array_before_inclusive
• firstval/first_value/lastval/last_value => nth (which allows negative values)
• natatime => in_groups or contains_only
• uniq/distinct => array_all_unique, array_all_same
• part => TODO
