That's absurd. You have no way to access private source code, so any decision on what features to exclude from future versions of Haskell must necessarily look at publicly accessible source code. The only alternative is to continuously add, and never remove, features from Haskell, even if no one (that we know) uses them. Moreover, the odds that everyone who is using n + k patterns are doing so only in private is an untestable hypothesis (i.e. unscientific) and extremely unlikely to be true. Regards, John A.

It *is* true that things that *are* used in the commonly available sources should continue to be supported in order to preserve the value of those commonly available sources.
