Meta

Convenience for introducing a symmetric Get/Put pair into implicit scope, and for deriving new symmetric pairs. It's important to understand that Meta should never be demanded by user methods; instead demand both Get and Put. The reason for this is that while Meta implies Get and Put, the presence of both Get and Put does *not* imply Meta.
