I don't understand something: if the null pointer was a billion dollar mistake, and has caused pain and system crashes for decades, then why weren't there any attempts to just not implement it in an object-oriented system?

Mixing #functionalprogramming and object oriented techniques in JavaScript is bad. I can easily see how someone exposed to this would think that #oop was inferior or frustrating. Someone only used to OOP is likely to feel the reverse.
@amoroso #clos #commonlisp #oop #lisp there was still a choice between various proposals then...
But the actual CLOS was not far away - the standard proposal was published in September 1988: https://dl.acm.org/toc/sigplan/1988/23/SI
Available above as a PDF. The final version was then published with the ANSI CL standard.
As installments of the ARTIFICIAL INTELLIGENCE column by Ernest Tello, in 1987 Dr. Dobb's Journal published a series of articles on OOP and object-oriented extensions for Common Lisp and Scheme. Back then CLOS was not yet on the radar but the Common Lisp extensions the articles covered already contained the main ideas of CLOS.

See how to iterate a composite dataset without exposing its internal logic. Its a combination of the composite and Iterator design patterns while implementing an office furniture system. It uses workstation as a composition of office chair, desk and cabinet.

The problem with object-oriented languages is they've got all this implicit environment that they carry around with them. You wanted a banana but what you got was a gorilla holding the banana and the entire jungle.

one of my favorite quotes about #OOP is that a class hierarchy isn't made to unleash your inner Linnaeus ;) - but this most certainly is: https://jillianhess.substack.com/p/carl-linnaeuss-note-taking-innovations - cute lil video about Linnaeus' note taking system. (As a german political scientist I'm course Luhmann's Zettelkasten inspired 
) Cool bits of information design however - If you love Tufte's book, you'll love this :))
The principle of data hiding in #OOP is an evil principle, for it seeks to instill a product/consumer dichotomy in the programmer's mind, and this is inherently hierarchical and #oopressive.
Object disoriented programming.

Fizz Buzz has just enough complexity to demonstrate a principle that is usually tough to understand through toy examples: the open/closed principle.

If you really must have plain #Perl #OOP methods with the same name that differ because of their argument signatures (also somewhat analogous to C++ function overloading), you can use Class::MultiMethods: https://metacpan.org/pod/Class::Multimethods

I’ve been reading Object-Oriented Analysis & Design With Applications (3e) this week. I’m only three chapters in but I can already say… “Where have you been my whole career?!”
