in thread How would I write this using map?

The code most likely works. Without knowing the object internals you really can not say what things the object contains and in what data structure. A hash is the most natural way to store data with objects so I would assume that things returns a hash.

    I can't see how this would work. I tried to create some mock code:
    use strict;

{
    package MyObj;

    sub new {
        my %obj; bless( \%obj, $_[0] ); return( \%obj );
    }

    sub items {
        my @things = ( 'key1' => 'v1', key2' => 'v2', );
        return( @things );
    }
}

my $myobj = MyObj->new();
print( "$_\n" ) foreach ( sort keys( $myobj->items() ) );

    but kept getting this error:
    Type of arg 1 to keys must be hash
(not subroutine entry) at /tmp/deleteme.pl
line 25, near ") ) "

    You cant return a hash from a function. Only lists and scalars.
