In Haskell, is there a built-in function that creates a list of one element?

Question

Looking for a built-in function that will do the following: ``` mklist x = [x] ``` The benefit is that I can use it in a composition to create a list of one element. Understand that (replicate 1) is available but is there a more direct function? Would be useful in situations like this: ``` ["Alice", "Bob", "Charlie"] >>= mklist . ("Hello " ++) ```

Accepted Answer

Monadic return:

```
return x
```

Or:

```
(:[]) x
```

It's less characters, but more shift-key usage, so might be harder to type.
