Secretly, all code wants to be spaghetti. You and your team have to put a conscious effort into prevent that from happening. Degrading the core of the language like this is like inoculating your homebrew with sewage and expecting it not to go wrong.
I never programmed in a team, so my experience of programming is probably very different from yours. You probably want something like electric cattle fencing (if I borrow your juicy language) for your team, but if I program for my self I just want an open field of Rye I can explore :)
But what exactly does this mean in relation that what are special forms in other languages are function calls in Rye?
Is the problem that you somebody could make their own control-structure-like functions? All these function calls have exactly the same evaluation rules, which is not something you can say about "special forms" in "normal" languages because special forms are exactly rules that break the regular evaluation rules.
Rye already has a lot of control-structure-like functions in it's standard library and many other functions that accept blocks of code and aren't related to control-structures. Yes, a "stupid" person can write "stupid" code in Rye, but you don't need much flexibility in any language to write stupid code.
I fully admit there are languages that are more suited for teams, and languages that are more suited for solo developers, for this reason.
That was also my point mentioning "million pixel website" because that "art" is directionless and crowdsourced and a painter can use the same pixels or even more flexible options to create beautiful images.
According to my own experience, it's entirely possible to write a rancid spaghetti carbonara all by yourself. I'm not saying you shouldn't do it (it's a heck of a learning experience) or it should be banned or prevented or anything. But if the language comes with a tin of e. coli, at least list the side effects.
I mean this is not the first dynamic, homoiconic, reflective language. Which one of these os something I didn't list is the obvious negative or e. coli as you call it?
> experimental
These ideas have been tried and tested for 60 years now and result in less spaghetti.
So degrading the core doesn't make much sense if you are not more specific. This is the core.
