People said that about Wirth's languages, too. Yet, metaprogramming, highly-optimizing compilers, REPL's, generics, concurrency models that were safe, Design-by-Contract, and so on all had their benefits that complicated implementation. In my opinion, some features like those were worth complicating implementations of languages since they simplified developers' work on every other project in that language. So, I'm always up for looking at new languages in case their experiments can teach us to do something better. Maybe it will simplify, complicate, or just refactor something in process. I don't care long as end result is better in a measurable way.

So, I'm as cautious about attempts to over-simplify things as I am to over-complicate them. Well, ok, I worry about over-complicating things more if it's programming we're talking about. I do try not to forget the other in the rare cases I think it might show up. ;)

Looking at my inspirations I would (take it with a grain of salt) say that Lisp and Forth are too simple, javascript is a mess (but with nice literal syntax for maps etc), Smalltalk is too complicated and Rebol is basically also a bit complicated and IMHO a bit of an oddball with some neat ideas. And Nim is a totally different beast.

Second-system effect?
