I may be stepping on language designers' toes here, but I always wanted
to ask this: (regardless of the functional programming examples), why
isn't it the case that a semicolon must always be present to end the
statement? I know that a change like this isn't feasible now, with all
the code that would be broken, but I just wanted to hear about the
rationale of this choice.
