Hello Chris,

No, but the functions you mentioned do fail immediately. If I use a head on an empty list I get an error immediately. If I use fromAscList incorrectly I get an error only when I try to lookup elements. This makes it hard to debug if you didn't make this error before. I don't mind a runtime error in this case, but I very much want to know where my bug is.
how about providing such check only in *debugging* version of library?
I think the decision whether to include specific check should be left up to the developer. Perhaps I would like to retain only a subset of checks, while debugging version restricts my freedom and I would end up writing my own version. Giving functions with and without checks is a good way of giving such freedom. Regards Christopher Skrzętnicki
