Delimited continuations as a programming construct were somewhat of interest when I learned about them, but not even my university discussed them. I don't think I ever had a colleague that even ever heard of the concept, let alone applied it. Of the "smart people", they typically only have heard of plain continuations, if you are lucky. The debugger in Racket was useful when I used it years ago. Unfortunately, it's k…
I have a similar picture so far in my work experience. Basically, none of my coworkers ever touched a lispy language. If I said words like "continuation", "environment of a closure", "continuation-passing style" or "macros and metaprogramming", I would get blank stares. Or if I complained about that lambdas in Python are stunted things, they would not understand, because they were only familiar with mainstream OOP and every noun a class paradigm and wouldn't get the ideas where to use lambdas or even inner/nested functions.
This kind of stuff is definitely not part of the usual CS curriculum at universities here (Germany). And of course even more pure fantasy to imagine that to be taught in any boot camps or other higher schools than universities.
Well, maybe some day I will work with people, who have this knowledge, and maaaaybe together we can make something happen employing the ideas and such a language, that implements these concepts well. Or even just work with people, who know FP and have explored building things with it, like I did.
