Possible bug (or mismatched documentation): eval blocks

[saurabhnanda]

The relevant section for Haskell eval blocks at https://theam.github.io/tintin/05-formatting-your-docs.html says:

Note that the result type must implement the Show type class, or else it will fail.

However, the following fails with a completely different error:

```haskell top
module Mod1 where
import Data.Text

foo :: Bool
foo = False
```

```haskell eval

foo
```

Error:

[ERROR] - CompilationError

Yup, that is a mistake indeed, will get it fixed ASAP
