Can anyone point me in the direction some call with continuation and stack and heap explainer? It would be great if it was brief and visual but I'm willing to read up. I just want to make sure that an explanation of call/cc is forthcoming.
This might help with continuations: https://en.wikipedia.org/wiki/Continuation
Here is a really simple example of simulating a C return using call/cc:
(display
(call/cc
(lambda (return)
(display "hello ")
(return "world")
(display "never reached"))))If you just want the simple explanation: A continuation is a copy of the return stack at the instant it was captured. When a continuation is invoked, that copy replaces the stack.
