I can't comment too much on this article, as I have a very, very limited view on LISP - basically just a couple of minor tutorials and one of the open-source interpreters. For me, it's always been one of those "I need to learn this" kind of languages, but I've never had a use case for it, and so it remains a curiosity to me more than anything.

I do know, though, that LISP allows the creation (or at least I have heard) for DSLs - so I am curious what people here think about this.

I'm also curious if anyone has an opinion on JetBrains MSL:

https://www.jetbrains.com/mps/

...and whether that would be a better thing to learn before or after learning LISP, as well as how it compares to LISP?

It's yet another "thing" that has caught my eye over the years, but again - no use case, and so it remains on the back burner for now...
