in reply to map grep and sort

Probably beyond the scope of "the basics", but List::Util::reduce sure is handy too sometimes. And although you have to load a module to use it, that module is part of the core Perl distribution.

See also: List::MoreUtils `part` (see Unusual sorting requirements; comparing three implementations.) List::MoreUtils `all`, `any`, `none` List::Util `first` `reverse` Also worth noting that `map`'s block is called in list context so can return zero or more items. `package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name`	[reply] [d/l] [select]

That is a very good and important point. Map can generate hashes because of this. I will add that fact to the above.	[reply]
