I think this depends on the language. For example Mathematics is generally accepted to be incomplete it what it can express (Gödel), and programming languages, while expressive and in theory turing complete, still limit the thoughts you can easily express, which I suspect will guide users to do things a certain way. Natural language is a bit different because of borrowed words and the flexibility of the humans parsing it.
