The unboxed tuple allows the value to be extracted from the IVar without being forced. If, however, we want QVars, we can always simulate that using accursedUnutterablePerformIO:
Actually, this might be silly, depending on implementation details. Twan's technique (which may or may not be directly relevant) overwrites a closure with its final value, which is a pretty good match for your approach. We still need to be able to implement tryRead[IQ]Var; I'm not sure what limitations that imposes.
