do.

Here is an example that proves that CPP is hard to support if possible at all.
Let's suppose that we want to format the following snippet of code:
```haskell
f = f1

Then, after formatting we get:
```haskell

Output after uncommenting CPP directives:
And finally, we uncomment CPP directives:
```haskell

Now the definition of `f` is broken when `C1` doesn't hold.
Thus CPP should not be supported and if CPP extension is enabled we should
signal an error right away.
Therefore, CPP should not be supported. If the CPP extension
is enabled, we should signal an error right away.
