DrRacket provides this, more or less. Rather than using the C-u 4 paradigm, though, it uses the "wrap-highlighted-text" paradigm.  So, in order to wrap the next three s-expressions with parens, I'd type shift-option-right right right, then type meta-(. On my keyboard, I have automatically paired parentheses enabled, so this last keystroke is just '('.  

(Insert obligatory RSI comments regarding shift-option here).
