Hi,
Reading on continuation I've came across this new style of creating the functions which I guess is not very clear in how it works
---------------
Prelude> let add_cps x y = \k -> k (x+y)
Prelude> add_cps 3 4 $ print
7
---------------
I have some questions as to
1) what is the role of variable 'k' and what eventually happens to it.
2) How does print work after the $ because there is clearly no parameter being passed to it.
Thanks,
