I would be more in favor of this proposal if the semicolon was not
optional. Having the ability to have code that is identical except for
a semicolon just doesn't feel right to me.

said that return values could already be ignored -- is my compiler just
out of date on this question?)
Right, this would be allowed.
By return values being ignored I mean that it's possible to write, say:
fn f() -> int {
return 3;
}
fn g() {
f();
f();
}
And the compiler won't complain or warn about the fact that the int
was dropped.
