You mean something like this, using hash to get all the statistics you need: 

use warnings;
use strict;

use File::Find qw(find);
use Data::Dumper;

# don't fix the directory
my $start_dir = $ARGV[0] || '.';
my $ext = qr[\.[^.]+];

find( \&finder => $start_dir );

my %file; # hash to collect statistics

sub finder {

    return if $_ eq '.';

    if (/($ext)/) {
        my $size = -s;
        $file{$1}++;
        $file{size}{$1} += $size;
    }
}

{
    local $Data::Dumper::Sortkeys = 1;
    print Dumper \%file;
}
