```
SafetyTier...<(_:_:)(minimum: Self, maximum: Self) -> Range<Self>
```

Returns a half-open range that contains its lower bound but not its upper bound.

Use the half-open range operator (`..<`) to create a range of any type
that conforms to the `Comparable` protocol. This example creates a
`Range<Double>` from zero up to, but not including, 5.0.

    let lessThanFive = 0.0..<5.0
    print(lessThanFive.contains(3.14))  // Prints "true"
    print(lessThanFive.contains(5.0))   // Prints "false"

- Parameters:
  - minimum: The lower bound for the range.
  - maximum: The upper bound for the range.

- Precondition: `minimum <= maximum`.
