Prediction: someone will make a reverse polish notation skill for interacting with claude claiming all sorts of things, like caveman, turn into another markdown as a service company, and make the news.
See Self's "dynamic deoptimization", where it constructs a virtual return stack on demand that you would have had, were it not for the JIT compiler's agressive inlining.

A different way to say the same: in forth, words get pushed on the stack, and popped from the stack by words that take arguments:

I Forth love
Forth love I
love I
Forth
; love presumably pops
; subject, object args
; from stack - and does something
; perhaps prints as side effect
Even oddly more pedantically, that's the operand stack, not to be confused with the separate return stack. >R and R> move values between the two stacks.
On the other hand, PostScript also has a dictionary stack, which you can use to implement a Smalltalk-like object oriented programming system. And its data types and executable code are basically polymorphic homoiconic JSON (like Lisp), not raw untyped bytes like FORTH.
Slightly OT, but nothing can beat DonHopkins’s “About” section here on HN [0].

FORTH LOVE? IF HONK THEN
My dad proudly flew one that said FORTH <3 IF HONK THEN. Yes, people did honk.

I present to you, the return-stack skill:

Amazing
is it me or is forth coming up a lot lately? or am i just having a plate-o-shrimp situation?
It does seem like it the last few days
Saw the same joke with Postscript many years ago.
Iがforthをloveする
Can someone explain for me?
A different way to say the same: in forth, words get pushed on the stack, and popped from the stack by words that take arguments:
Is that loss?
No.
well played
Here is some inexplicably but meticulously formatted FORTH code that uses right justified indentation! Including reverse polish notation assembley.

Forth I assume uses reverse polish notation: arguments before the operator.
3 4 +
for example, would return 7.
> would return 7
more pedantically, it would push 7 onto the stack
even more pedantically, would remove 3 and 4 from the stack before pushing 7
Even oddly more pedantically, that's the operand stack, not to be confused with the separate return stack. >R and R> move values between the two stacks.

The stack is really a convenience that makes pipeline-driven programming possible in the language.
somewhat relatedly, shell pipelining is very amenable to being massaged into (non stack-based) concatenative programming
Forth uses RPN so the "verb" is last.
That is, you provide the data first (I and Forth) and the command (heart) last.
I found https://www.explainxkcd.com/wiki/index.php/Main_Page quite useful for that.
FYI: Forth can be very readable!
IT DOES NOT NEED TO BR ALL IN ONE LINE
Most commercial forth source code is totally readable and maintainable:
comments, newlines, macros, high level commands etc
It's a total myth that its 'write only'. The same nonsense is spreaded by some nerds who actaully never wrote a single program in it.
ps. same goes to COBOL. 99% of fud by guys who never even wrote a simple program in it.
That beautiful is.
I first thought this was some spin on May the fourth be with you. As in how Yoda might say it.
My brain tells me Yoda speak would likely be: love Forth, I do.
But then he would also say: Forth is the path to the Light Side…
I doubt yoda speak is actually strict enough, but I do enjoy the idea that Yoda comes from a reverse Polish civilization.
Master Yoda's speech, secret solved is; an old Forth programmer is he simply.
