`unsupported[forbid-form]`

A FORBID with arguments, or without a condition or source tag.

FORBID action WHEN condition [SOURCE:id]. FORBID action() with empty parentheses is the same clause.

Example

Through compileSource

CONTRACT Claim {
  ENFORCEMENT_MODE: enforced
  CONTEXT {
    ENTITIES Request {
      count: int
      region: string
      ready: bool
      ratio: float
    }
    CONSTANTS {
      zero: int == 0 [SOURCE:POLICY]
      cap: int == 25 [SOURCE:POLICY]
    }
  }
  TRIGGER {
    grant()
  }
  GUARANTEE {
    ENSURE grant() WHEN Request.ready == true [SOURCE:must_be_ready]
  }
  PROHIBITION {
    FORBID grant WHEN Request.count > cap
  }
}

      cap: int == 25 [SOURCE:POLICY]
    }
  }
  TRIGGER {
    grant()
  }
  GUARANTEE {
    ENSURE grant() WHEN Request.ready == true [SOURCE:must_be_ready]
  }
  PROHIBITION {
    FORBID grant WHEN Request.count > cap [SOURCE:over_cap]
