      globals: Statements [
        Variable { type: 'boolean', name: 'flipped', value: false }
      ]
    },
    EmptyLine {},
    JASSFunction {
      name: 'flip',
      statements: Statements [
        Variable {

          name: 'previousState',
          value: [String (Name): 'flipped']
        },
