Proposal: AsyncFunction
To make it easier to constrain a type to be an async function. We can currently do T extends Function, but there's no way to enforce it to be async.
We already have an internal type for this:
But I'm thinking it could be more reusable:
type AsyncFunction<Arguments extends readonly any[] = readonly any[], ReturnValue = unknown> = (...arguments_: Arguments) => Promise<ReturnValue>;Thoughts?
