everybody remembers THAT precedence rule
I have fixed multiple bugs over the years caused by people thinking that + had higher precedence than *, or that C was strict left- or even right-associative. Yes, anyone with half a clue knows otherwise: but not every developer, alas, has half a clue to spare.

Also, clue level can vary significantly, even with a fixed, given programmer. E.g. regular diurnal patterns (pre-coffee, post-lunch, pre-knocking-off-time), when extremely tired at the end of a too-long hacking session, or even programming while drunk. :)

The solution to that isn't dumbing down the language but firing people who don't have half a clue.

Scheme is the ultimately dumbed-down language for the computer, to the degree that it does not require a parser for interpreting, just an expression reader and an evaluator.

It is similarly dumbed-down to the human reader as commerce/Pidgin English is, meaning that it takes practice and control to consistently dumb down in the right manner. The purpose is having a common language for talking about programs shared between human and computer.

Using infix in Scheme is like Yodish Pidgin English. Sort of defeats the original purpose of human and computer sharing a language for talking about code rather than humans expressing themselves to one another.

What a wonderful instance of "Humans can do the work, so machines have time to think."

> Scheme is the ultimately dumbed-down language for the computer,
No, it's not. As you were told multiple times by now, Scheme already has syntactic sugar for multiple constructs. 'x is (quote x), and (quote x) is (quote . (x . ())).

No, it doesn't. What makes Lisp Lisp is the ability to easily represent a program in the language's primary data structure and manipulate it. Infix syntax doesn't change that, it just makes things more readable. Again, you were told this multiple times, so I don't even know why I repeat it again. It's really a waste of time to argue with a stick-in-the-mud like you.

Not quite. The problem, in a sense, is that the structure chosen for representing program makes sense for optimizing interpreter a bit, at the cost of being very unnatural. Subtrees are not subexpressions. Sure, that way you avoid digging in to find the node where you'll be doing reduction, but that doesn't come for free. As the matter of fact (and you damn well know that, seeing that you seem to be familiar with e.g. Haskell), the things can be done the other way round - with APPLY being the fundamental primitive and CONS expressed via it. The same "easily represent program in the language's primary data structure" thing holds for a lot more than just LISP, e.g. when the primary data structure *is* partially evaluated expression. That's not what makes LISP LISP; neither is the syntax, of course.
