# GreaterOrEqual

Values which implement the `>=` infix operator must implement this protocol.

If the value also implements the `Greater` and `Equality` protocols then this protocol can be automatically implemented.
```
protocol GreaterOrEqual, requires: Greater + Equality, as: do
  ```doc
  Compare `self` and `other` returning a boolean.

  The default implementation delegates to the `Greater` and `Equality` protocols, however you should probably implement this function as a single comparison is more than likely much faster.
  ```
  def greater_or_equal?(self: Self, other: Any): Boolean, when: Greater.greater?(self, other), as: true
  def greater_or_equal?(self: Self, other: Any): Boolean, when: Equality.equal?(self, other), as: true
  def greater_or_equal?(_self: Self, _other: Any): Boolean, as: false
