Added enum example in variables section.

No description provided.

What is the motivation behind this enum being string-based?
It is then arguable that it has advantage over bad example with just constants.

Would it be better maybe to use constant member, like:

enum Genre {
  Romantic,
  Drama,
  ...
}

[lucavictor220]

I rethought the intent and motivation of enum.

[dimadeveatii]

Much better now!
Please fix only the small typo I suggested in comments.
