"Lisp doesn't exist" is also kind of wrong but with conviction, or at least debatable. Lisp was standardized in 1994 as ANSI Common Lisp, and there are a handful of other Lisp-like languages. And pure languages aren't useless. Not being able to do I/O can be good for many purposes. Pure Haskell is still able to model computations involving I/O, which are then executed by a trusted external runtime. There are benefits to disallowing arbitrary effects, which is also why several new languages take purity even further and disallow infinite recursion. |
