Full stack web development is a multi-discipline area that demands a high level
of knowledge and skill to architect a working application. IMO, the vast
majority of all web developers are not qualified to be doing it.
We, ourselves, might be able to improve this situation, with education,

Suppose I've defined a simple language:
; example.rkt
#lang racket
(provide foo)
(define-syntax foo
(syntax-rules ()
((foo)
(printf "foo!~n"
Now I want to create an eval-example function which will evaluate forms in
my language:
> (eval-example '(foo))
foo!
If I'm working

They need continuations, because BACK buttons, cloning of TABs and similar
actions force a control flow on interactive

They need continuations, because BACK buttons, cloning of TABs and similar
actions force a control flow on interactive web programs that is easily
explained and programmed
Thanks! Very informative! I have some more questions but I should
google them responsibly first☺️

You can't necessarily turn recursion into a loop using only TCE.
TCE turns an ordinary call/return sequence into a non-returning jump [or
fall through

Racket does tail call elimination [as
Please call it “proper implementation of tail calls (PITCH)”. The others got it
wrong.

As a descendant of Scheme, Racket has proper tail calls. Beyond that, in
Racket, "there is no such thing as stack overflow; you can run out of
memory if a computation involves too much context, but exhausting memory
typically requires orders of magnitude deeper recursion than would trigger
a stack

recursion, but any tail calls. If not, how about mutual tail recursion (where
