    Here's another thing I believe: The next mainstream programming language (or family of them) will have functional-logic underpinnings like backtracking, unification, and failure. The move will be driven by the improvements in writing code that's concise, correct, and verifiable.

        Will it finally have totally automatic string handling that doesn't involve counting characters and adding 0 like early 70's assembler? The inexcusable "feature" that makes everything unsafe.

        Curry is the most-developed FLP language so far. However, it's still sort of a half-way step, which doesn't fully embrace first-class failure (and still exposes boolean ops), and doesn't use backtracking for loop iteration. https://www-ps.informatik.uni-kiel.de/currywiki/

        I still find it highly amusing that functional languages start from an ideal of being stateless, with no variables. Then the usable ones hack in some way to store some state info, so that you could actually do useful stuff - & maybe even varying, which I hear is good for games!

        You can implement a principled functional language with state. It ends up treating state and processes as similar. Trick is that STLC "return a value" introduces linearity. You extend that property by constraining contraction. See. Affine logic, Linear logic, Session types.

        In the early '00s it was proven that linguistic abstractions and various forms of decomposition cannot make verification easy (and BTW, in practice, the languages that have so far had the best success in terms of both formal and informal verification are synchronous languages)

        Yes, the general case of verification is theorem-proving. The ultimate language ultimately support that, but ought to also make it much easier than present to adopt small-scale verification easily.
