What is wrong with 8th's license? It is basically a Forth, so extremely interactive...mostly just messing with a stack...not sure about metaprogramming. I think a production license costs you $200 as a one time fee and you have to pay no royalties or anything for apps (better than many tools out there). Upgrading to a later version comes at a discount too. Most of the runtime is proprietary/closed-source if that is what you were saying (def understandable if you had a problem with that). Also, being a 1-developer project, progress is rapid, but I'd be worried about what happens if the maintainer wins the lottery.

Any language with a REPL can be described as "interactive" but that's not what having a strong focus on interactive development means. As Mikel Evins wrote, it's really about the entirety of a language being geared around interactive development.

I can't blame you for parsing it the other way; it's a more likely spelling. You can blame my eccentric father for the odd spelling of my first name, but he inherited the surname fair and square.

It's pronounced exactly the same way as "Michael Evans."

It's been a while, thanks for making it happen!

I 100% agree that it seems like you can't unwind the stack the same way you can in Common Lisp or Smalltalk though.
