Just because such code parses, it doesn't mean you should write that way. Rather than requiring a ludicrously dense or terse style, most real projects will just have fairly reasonable coding standards (whether formally specified or just commonly understood) and expect you to exercise good judgment. Besides, I don't think anybody is really expecting you to cram as much into one line as possible.
