The first tile in my life I see such strange definition of expression :)
Please, use more generic notions.

As I said, "return" statement is a good example. The assignment one too.

And the principal difference between statement and expression that the 
expression doesn't control execution flow.
As you can see, iif "expression" does.

In C the "?" statement called operator, it may be a good compromise.
