  I found and typechecked these definitions in scratch.u. If you
  do an `add` or `update`, here's how your codebase would
  change:
  
    ⍟ These new definitions are ok to `add`:
    
      `()`.foo : ##Text

```
``` ucm
scratch/main> add

  ⍟ I've added these definitions:
  
    `()`.foo : ##Text

scratch/main> find

  1. `()`.foo : ##Text
  

scratch/main> find-in `()`

  1. foo : ##Text
  

scratch/main> delete.namespace `()`

  Done.
