Using grep and map in a void context is generally discouraged. A for statement modifier is usually clearer, and almost always faster.

use strict;
use warnings;
use Data::Dumper;

my @array = qw(John Sue Larry Mary John Mary Larry John Joe Lisa John 
+Mary);

my %count;
$count{$_}++ for @array;

print Dumper \%count;
