Enums are unimplemented

[egroge]

Enum parsing is implemented according to the flint guide.

However beyond this enums are not implemented in flint:

Semantic analysis

At the semantic analysis stage, a variable can have an enum type. For example, the following is permitted:

enum Colour: Int {
  case Red
  case Blue
  case Green
}

contract A {}

A :: (any) {
  public init() {}

  func id(colour: Colour) {
    // Do something
  }
}

However, semantic analysis does not yet allow access via the dot operator to particular variations of the enum. That is to say that Colour.Red would fail semantic analysis.
