/// A container for storing action filters.

/// The logic behind having this rather than a normal closure is that it allows us to namespace and gather action filters together in a consistent manner.
/// - Note: You should be adding extensions in your modules and exposing common filters you might want to use to focus your debugging work, e.g.
/// ```swift
/// extension ActionFilter where Action == AppAction {
// A URLSession extension that fetches data from a URL and decodes to some Decodable type.
// Usage: let user = try await URLSession.shared.decode(UserData.self, from: someURL)

/// A scroll view that allows scrolling using a hardware keyboard like `NSScrollView`.
/// Supports arrow keys, option + arrow keys, command + arrow keys, space bar, page up, page down, home and end.
/// Limitations:
/// - Paging scroll views (isPagingEnabled = true) are not supported yet.
/// - The scroll view must become its own delegate so setting the delegate is not supported yet.
