Related ethereum/EIPs#62. It could also be replaced with special LOGs, which are not rolled back at execution errors. See ethereum/EIPs#120 for an implementation of moving LOGs to storage.

Assuming we change return so that the value is not rolled back on a VM error that could work. However that introduces a discrepancy with how EVM expects it.
