I just can't seem to ever understand map. I know the two for loops below could be rewriten with map. Could someone help me out here? 
#!/usr/local/bin/perl -w
use strict;

my %byFile;

for (<DATA>) {
        my ( $size, $name ) = split /\s+/;
        $byFile{$name} = $size;
}

for ( keys %byFile ) {
        print "$_\t=>$byFile{$_}\n";
}
__DATA__

Thanks!
<update>Sorry for not be clearer in the first place, but I do need to use %byFile for other purposes. The script I posted just demostrates some isolated code I have in another script.
