Collecting AnyCancellable tokens in declarative SwiftUI fashion

CancelBag.swift

// Copyright © 2019 Alexey Naumov. MIT License

import Combine

typealias CancelBag = Set<AnyCancellable>

extension CancelBag {
    mutating func collect(@Builder _ cancellables: () -> [AnyCancellable]) {
        formUnion(cancellables())
    }

    @_functionBuilder
    struct Builder {
        static func buildBlock(_ cancellables: AnyCancellable...) -> [AnyCancellable] {
            return cancellables
        }
    }
}

Can you please share an example of how to use this?
