Call async from Node code

[atollk]

Hi. In Godot C# and GDScript I found that it's pretty common to mix sync and async code, e.g. https://docs.godotengine.org/en/stable/getting_started/first_2d_game/06.heads_up_display.html

How can that behavior be replicated in SwiftGodot? Wrapping the call to the async function with a Task doesn't work for most cases:

        Task {
            await self.onPlayerHit()
        }

passing closure as a 'sending' parameter risks causing data races between code in the current task and concurrent execution of the closure

(I'm not too familiar with Swift as a whole, so maybe this isn't a SwiftGodot-specific issue?)
