Swift Macros: Rewrite block to add weak capture?

Hi, I thought I'd ask as this sounds like the perfect use for Swift Macros and I'm betting other people ran into the same issue :)

I'm currently trying to simplify [weak self] captures in some of my code. For example:

// Usual syntax
someAlert.addTextField { [weak self] textField in
    guard let self else { return }
    textField.text = somethingInSelf()
}

Adding a macro seems to trade one kind of wordiness for another:

// Using a macro works, but is wordy because it requires non-trailing syntax
someAlert.addTextField(configurationHandler: #weakSelf { textField in
    textField.text = somethingInSelf()
})

Ideally I imagine there must be a way to do something like the code below:

// Using the same macro fails when applied to a trailing closure
someAlert.addTextField #weakSelf { textField in
    textField.text = somethingInSelf()
}

Does anyone have any suggestions? I feel this is probably a known/solved problem and I'm being a bit slow on the uptake :D
