OOP language aren't explicit in what function is pure. If I'm working on a 10MLoC project and touching hundreds of methods while working I can't lookup the impl

OOP language aren't explicit in what function is pure. If I'm working on a 10MLoC project and touching hundreds of methods while working I can't lookup the implementation of each one to determine whether they are pure. And no a comment saying they are pure is not sufficient. The above is trivial in FP languages.

Well, except D, D has a @pure annotation :)

  D pure function aren't really pure though. They can modify the arguments that are passed in. Great concept otherwise.
