Review Comment:
Reading the code comment
```
/**
* A higher order function takes one or more (lambda) functions and applies
these to some objects.
* The function produces a number of variables which can be consumed by some
lambda function.
*/
```
I think for use-facing error message, we can just say "higher order
functions". For the code change, we can check both `HigherOrderFunction` and
`LambdaFunction` to be safe.
