TheLemonMan: like this ? "List.fold_left (fun x y -> x y) (fun x -> x) lst"
<Armael>
you probably want fold_right instead
<Armael>
let composel lst = List.fold_right (fun f acc -> (fun x -> f (acc x))) lst (fun x -> x);;
<Armael>
(it didn't work because in the body of the fold, you were trying to apply the accumulator (of type foo -> foo) to a function of the list (also of type foo -> foo))
<jcelerier1>
ah, yes, we have to return an actual function
<jcelerier1>
I understand, thanks Armael & TheLemonMan !
<Armael>
(instead you want to compose them, ie (fun x -> f (acc x))

Fardale: well, I don't know but when I run in the interpreter it certainly prints out whatever I type in
<Fardale>
because the interpreter call a print function to print the result
<Fardale>
There no magic if you want to print something you have to call a print function

jcelerier1: you can use ppx_deriving.show to generate show functions for you
<Leonidas>
jcelerier1: or use companion_cube's containers, which has a library to compose printers which is sort of neat
<Leonidas>
(sort of neat as in "boy I wish we just had the Show typeclass, but this is the next best thing")
