### Demonstrate Concurrency Capture Error

Source: https://developer.apple.com/documentation/swift/sendablemetatype

An example showing how capturing a non-Sendable metatype in a concurrent task causes a compiler error.

```swift
protocol P {
  static func f()
}


func useFromAnotherTask<T: P>(_: T.Type) {
  Task { @concurrent in
    T.f()   // error: capturing non-Sendable type `T.Type` in a concurrently-executing task
  }
}
```

### Description
Swift provides a `Regex` struct for working with regular expressions. This includes types for specifying repetition behavior (`RegexRepetitionBehavior`), semantic matching levels (`RegexSemanticLevel`), word boundary kinds (`RegexWordBoundaryKind`), and type-erased regex output (`AnyRegexOutput`). The `RegexComponent` protocol defines types that can be part of a regular expression.

### Types
- `struct Regex`: Represents a regular expression.
- `struct RegexRepetitionBehavior`: Specifies quantifier matching behavior.
- `struct RegexSemanticLevel`: Defines semantic level for regex matching.
- `struct RegexWordBoundaryKind`: Algorithm for word boundary matching.
- `struct AnyRegexOutput`: Type-erased output of a regex match.
- `protocol RegexComponent`: Represents a component of a regular expression.

### withUnsafeContinuation(isolation:_:) Function

Source: https://developer.apple.com/documentation/swift/withunsafecontinuation%28isolation%3A_%3A%29

Invokes a closure with an unsafe continuation for the current task, allowing manual control over task suspension and resumption.

```APIDOC
## Function: withUnsafeContinuation(isolation:_:)

### Description
Invokes the passed in closure with an unsafe continuation for the current task. The body of the closure executes synchronously on the calling task, and once it returns, the calling task is suspended until the continuation is resumed.

### Signature
```swift
func withUnsafeContinuation<T>(
    isolation: isolated (any Actor)? = #isolation,
    _ fn: (UnsafeContinuation<T, Never>) -> Void
) async -> sending T
```

### Parameters
- **isolation** (isolated (any Actor)?) - Optional - The actor isolation for the closure.
- **fn** ((UnsafeContinuation<T, Never>) -> Void) - Required - A closure that takes an UnsafeContinuation parameter. You must invoke the continuation’s resume method exactly once.

### Return Value
- **T** - The value the continuation is resumed with.

### Discussion
Unlike the 'checked' continuation variant, the UnsafeContinuation does not detect or diagnose misuse, such as calling resume twice or forgetting to call it. Failure to resume the continuation will cause the calling task to remain suspended indefinitely.
