Btw, small bone to pick with the Pact whitepaper[1]:

> EVM and Solidity have no support for atomic execution. Ethereum contracts simply abort on error, leaving developers with the impossible task of undoing previous writes and contract creates after any possible error condition.

EVM transactions are atomic; all state changes are reverted on aborts (out-of-gas errors and throws). Ethereum state changes are committed only after successful transaction execution, so developers never have to worry about writes from half-executed transactions.
