@tailrec is also bad

[valtih1978]

@tailrec kills error reporting likewise unspecified overriding does. Once I add this attribute, code stops execuing in worksheet.

object o2 {
    @tailrec def f {if (false) f}
    1
}

Environment is the same.

Actually, this is a duplicate of #214. It seems to me that it doesn't matter how you create an error, the only thing that matters is that an error exists and that the worksheet doesn't show it.
