--- Comment #1 from Richard Cattermole <alphaglosined at gmail.com> ---
Not a regression in rdmd.

In dmd 2.104.0 empty statements with semicolons now error.

You do not need anything passed to the eval flag and it would not emit the
semicolon.

However in saying that, rdmd in innerEvalCode should be made smarter so that it
checks if last character is either a semicolon or a close brace, rather than
just a semicolon. That way loops can work.

I suppose making it even smarter with comment detection ext. would be good too.
