Async property getters/setters

[ekolis]

Since property getters and setters are syntactic sugar for methods, I'd like to be able to declare getters and setters as async:

public int SomeCachedThing
{
    get => someCachedValue;
    async set => await StoreItInCache(value);
}

If this happen, it should be the whole property async.
In compound operators (await SomeCachedThing += 1) doesn't make sense to await a sync accessor.

Properties really shouldn't be used for fallible I/O operations that would necessitate async.

Agree. Properties are supposed to be nothing more than fancier fields.

Agreed, and I think I'd rather see await SetSomeCachedThingAsync(42); than await SomeCachedThing = 42;.

(Not to mention, await SomeCachedTask = someTask; has a meaning today)
