[Swift-devel] swift write once array/struct

[Ketan Maheshwari]

Hi,

So, in the meeting today, I was curious about wether the Swift write once
array/struct property is enforced via some external function or is it
intrinsic to the array/struct.

In other words, is  the array/struct implemented in such a way that it will
automatically not allow anything to write once its i-th item has been
written or some external entity keeps track of this property and gets
triggered every time a write happens.

I thought with intrinsic property, write operations will be atomic and free
of deadlocks as opposed to externally tracked/enforced property.
