I think I see the cause of the disagreement: there is no such thing as an 
"implicit" contract. Either it is part of the explicit contract, or it 
doesn't exist and it has to be checked somehow -- because programmers are 
human and they *will* make mistakes or even be incompetent.

*Ada* is deficient in the ability to write proper contracts (improving this 
is a primary driving force behind Ada 2012, after all), C is even worse in 
this respect.

An implicit contract is the same as assuming something, and we all know what 
"assume" does: it makes an "a**" of "you"and "me". :-)
