You could have an IDE and build system that makes signatures, 
unit tests and pre/post conditions essentially read only. Then 
any modifications to the program specification is either 
impossible or is flagged as something that is up for negotiation. 
The build system/compiler can trivially emit contracts to a 
database. If the contracts change then all code that depend on 
them will have to be revalidated/recompiled.

It is important for D that the D developers keep in mind that the 
language and the compiler should be designed as separate 
entities. DMD-internals have too much influence over the language 
design already.
