While a modular analysis does require extra specifications,the benefit
is that the analysis can be performed fast enough to be run after every
They use the "plug-in pre- and post-conditions"
to validate SQL statements at compile-time. Pretty neat.
Fugue builds on our previous work on the Vault programmming language,
which in turn is based on type-state checking and the Capability
Calculus. ... Fugue’s main innovations over Vault are state mapping,
custom states, and plug-in pre- and postconditions, for which Vault has

Metal, and Prefix.
