Hello Jeff,
I do have a question now. I've written an (at the bottom of this message) example on using a protected type.
My current understanding is that the protected type is a way to encapsulate a piece of data and then regulate which values can be assigned its insides (similar to how in Java there is a way to create a piece of code where only one thread at a time can run at any given moment.) The example below has 5 tasks and each one tries to update the same unbounded string. The goal was to create a small application with 5 tasks and each one fighting to update the same value.
Does my description make sense? Or am I completely off-base?
