  Loading changes detected in scratch.u.

  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.add      : Int -> Int -> Int
      foo.subtract : Int -> Int -> Int

```
``` ucm
test-5055/main> add

  ⍟ I've added these definitions:
  
    foo.add      : Int -> Int -> Int
    foo.subtract : Int -> Int -> Int

test-5055/main> ls foo

  1. add      (Int -> Int -> Int)
  2. subtract (Int -> Int -> Int)

test-5055/main> view 1

  foo.add : Int -> Int -> Int
  foo.add x y =
    use Int +
    x + y

```
