the logic is that it will break out of the `each` loop if `s3_acl.allow_read_access_from_accounts` returns `false` because we don't want to continue checking each region for a valid account.

i thought about doing something like this instead, what do you think?

`break unless able_to_grant_read_access?`

```
private
def able_to_grant_read_access?
    @s3_acl.allow_read_access_from_accounts :key_name   => @key_name,
                                                                     :key_folder => @name,
                                                                     :accounts   => @accounts,
                                                                     :bucket     => @bucket
end

def s3_acl
    @s3_acl = ACL::S3.new :config => @config,
                                         :region => @region
end
