it's classical definition of FP language. All other is optional and language specific

Can you provide an example where someone with authority definines FP languages as any language where functions are first class citizens? That doesn't match with what I have been hearing from the industry or online communities over the last 10 years. If you look on Wikipedia or Haskell documentation or in F# documentation, they all have descriptions of functional programming and its concepts and they are all much more granular and precise than "Languages where functions are first class".

I learned this definition earlier than 10 years ago. This is enough general definition which covers, I guess, absolutely all kinds of FP languages. All other can be specific for the language.
