I can see this being useful for certain financial contracts that are: a) not completely standardized b) based on a linear combination of standardized terms, and c) with all conditional terms based on objective external references (i.e. price of a dec 2016 corn contract on the Chicago Board of Trade). The advantages would be that a contract compiler could enforce certain meta-rules, and the contract itself could be entered into an automatic settlement system rather than instructions based on the contract. I'd expect even in that case the canonical form would still be the English language output rather than the source code.

But for any arbitrary contract, I agree, I don't see it at all. At least not anytime soon.
