Put it all on one line then! :) I just grepped some of my C/C++ code and my one-liners consistently look like this:

virtual const std::string& getCommand() const throw() { return m_command ; }

Yeah, that works for really short methods, but for anything even a little more complex you're just replacing vertical scrolling with horizontal scrolling.

That's true for one-liners in any language.

Not necessarily. In Haskell the oneliners are frequently short enough to fit on one screen.

For example, I recently needed to do some Run-Length Encoding:

    import Control.Arrow
    import Data.List
    
    encodeRLE :: (Eq a) => [a] -> [(Int, a)]
    encodeRLE = map (length &&& head) . group
    
    decodeRLE :: [(Int, a)] -> [a]
    decodeRLE = concatMap (uncurry replicate)
