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).
