[parenscript-devel] A simpler way to do multiple value return? (Was: PS test failures in 7be9b45)

Yes, that's currently the only way I see to do it. This issue is
orthogonal to how the multiple values are passed - in principle I
could have implemented the multiple value passing instrumentation
right after adding the return instrumentation code, but it didn't
occur to me at the time.

So to clarify, my proposal has two separate components:
1. Pass multiple values on the callee function object
2. Instrument every tail call
