Well, if works in that it returns the result of the last expression evaluated. It seems that's what looping constructs should do too. Wouldn't it make sense for this sub x { $_ for 10 } to return 10?
Not really. If you're asking my opinion I'd say it should be an error if the sub is called in anything other than a void context. Note the following are also compilation errors... 

my $what = (if(1){print "true"}else{print "false"});

sub foo
{
    return (for (1..3) { print $_ });
}

You're not arguing that they shouldn't be, are you?
