Both the documentation and name of this function is incorrect now that the underlying functionality has changed - would you mind updating it to something more appropriate @Fznamznon? It used to return the character itself:
```
  /// Given a Token \p Tok that is a numeric constant with length 1,
  /// return the character.
```

But now returns the value of the character.
