// setVariable works on non-innermost environments.

// (The debuggee code here is a bit convoluted to defeat optimizations that

// could make obj.b a null closure or obj.i a flat closure--that is, a function

// that gets a frozen copy of i instead of a reference to the runtime

// environment that contains it. setVariable does not currently detect this

// flat closure case.)
