Re: FTP as a whole
The FTP on the whole was and remains overwhelmingly popular. Frankly, the vast majority, not all, but most of the users complaining in this thread are the same people who were complaining about the FTP in the first place, rehashing precisely the same arguments. The FTP itself passed with an overwhelming 82% majority. If we can't act in the presence of that large of a public majority, when _can_ we act?
It's certainly comfortable to argue this way if your opinion is that of the majority. In the library submissions process [1] it is acknowledged that a majority vote needs not to be the final criterion. I think it would be better to work towards a consensus. The consensus here could be: We acknowledge different styles of programming and therefore different expectations to the compiler. Some programmers consider it a bug if 'length' is defined on tuples, other ones consider it a useful feature. In order to serve both sides we add warnings for those who want them. But these warnings should be bundled together with the instance additions and not deferred indefinitely. [1] https://wiki.haskell.org/Library_submissions
