the school I went used to teach C, Python and Scheme in the first year (nowadays it's C, Python and Racket). I don't think I remember more than one or two people actually liking the LISP experience, how bad it was when comparing to other languages is actually a common joke subject amongst alumni.
The issue with the line of reasoning that “X language is bad because it was bad during an intro programming class” is that your experiences in that class do not generalize well. Sure, python might be better for writing some basic algorithm that you fully understand before writing a single line of code, and for fairly small codebases. However, try writing a large codebase and you’ll realize that, for example, managing state is really hard.
Sure, racket and other functional languages might require a greater learning curve than other languages, and of course they’re not the language of choice for performance critical applications (nor will Matthias Felleisen claim it is). However, as a systems developer who uses almost exclusively C++, I would argue that starting out with a language that forces you to think about your contracts, mutability, scope, etc, invariable create a better programmer down the line
A lot of the time when you meet someone who had a bad experience with Lisp, if you interview them a bit, you soon discover it was actually Scheme.
Scheme twenty years ago, R5RS was even worse than now. It had nothing practical in the spec. No way to write a program consisting of multiple files. No error handling. R5RS talks about situations that trigger an "error", but nothing about how such a thing can be handled and recovered. Or how an error can be generated on purpose and then caught.
Anyone who studied R5RS in school was learning an utter piece of academic garbage; a serious regression from real Lisp.
Functional programming of course maps (heh) very cleanly to this line of thought.
But most people hate maths and this way of thinking. In contrast, you get first year students "re-discovering" OOP ever year - for instance a common trick to make them learn design patterns is just to put a problem that calls for it in front of them, and three times out of four in my experience they will even come up with a pattern name close to the original ones.
It is however pretty easy to implement something like racket's for loops on scheme using lower level macros, and there are some available.
Implementing something like common lisps iter is actually not very hard, and even improving upon racket's for loops is far from complex.
I believe that Scheme's DO is looping.
