```ruby
Util::Puppet.config_value("org_label").tap { |s| s.replace 'ACME_Corporation' if s.blank? }
# or
default = lambda { |default, str| str.replace default if str.blank? }.curry
first_org_name = Util::Puppet.config_value("org_name").tap &default['ACME_Corporation']
first_org_label = Util::Puppet.config_value("org_label").tap &default['ACME_Corporation']
# ...
```
