           Summary: Misleading error message against the contract followed
                    by semicolon in interface

I've hit this three times, and each time I wondered "The grammer gets changed?
"
Too misleading message.


interface I {
    void funA();

    void funB(int n)
    in {
        assert(n);
    }; // --- unexpected semicolon
}

Error: missing body { ... } after in or out



It's sure that the last semicolon is unexpected.
And I know this error is proper for _class_.

However, when turning funA into funB, we likely forget to remove the semicolon.
As a result, it is possible for people to mistake "Interface with contract is
illegal".
