You write something, Agda2 checks it and says that you forget something, you wrote an inconsistent code or you wrote ambiguous code (it is possible to hide some parts of code).
It was half-joke, actually -- but there is point to it, to some extent.
I was referring to the fact that (web) search engines often display `Did you mean X?' when query string contains a symbol they don't know. Also, in a way, a search engine does interpret the query as a (simplistic) program of sorts. And, once in a while, it'd be handy to be able to issue query to search engines in a more powerful query language... So I saw a weak analogy there, between search engine and a compiler with the `Did you mean X?' feature.
You appear to be confusing "Turing complete" and the "Turing test". These two concepts are only related by the man which proposed them. They are quite separate classes of concept.
