| # Show how to implement Java-like method annotations in Ruby. This example shows how to create | |
| # something more like Ruby's own private and public annotations, where each method that's declared | |
| # afterwards has its visibility set to private/public. | |
| # | |
| # To make this work more like a Java annotation (works for only one method), then you just have | |
| # to @_admin_only to nil in the "unless" condition from #method_added | |
