创建UCM成绩单时,如何查看计算项目?

鉴于以下成绩单:

```ucm:hide
.> pull https://github.com/unisonweb/base:v3:.releases._latest .base
```

```unison
foo = List.map (x -> x * 2) [1,2,3]
```


```ucm
.> add foo
.> view foo
```

执行此操作时,我得到以下输出:

```unison
foo = List.map (x -> x * 2) [1,2,3]
```

```ucm

  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 : [Nat]

```
```ucm
.> add foo

  ⍟ I've added these definitions:
  
    foo : [Nat]

.> view foo

  foo : [Nat]
  foo =
    use Nat *
    List.map (x -> x * 2) [1, 2, 3]

```

我理解为什么会这样,但是否有其他方法可以显示 foo (即。 [2, 4, 6 ]),就好像我们在 scratch.u 文件

我还尝试了:

```ucm
.> foo

```

但是得到错误 I don't know how to foo. .
