Was tinkering with the Rust concept of 'forcing' a larger size integer type into a smaller size type* and I could not figure out why the compiler seemed to keep complaining even after I applied the suggested hint.

x + y is the return expression** and I needed to call try_into() on the whole thing and the following is (now) obviously calling it on the y.

x + y.try_into().unwrap()

So now this works...

(x + y).try_into().unwrap()

* - I would not program this way, trying to stuff something larger into something smaller, but just for the exercise of it

** - is 'expression' the correct term here?
