Answer 1

this link may help you to understand how to use reduce() for compositing:

Answer 2

visph thats actually what I wanted.
But why does my way not work?
I reduce a value with a function and get a value again. Val,func
The link does the same with func,func

Answer 3

actually you pass to callme() two functions, while it expect one arg and one function: you are skipping the compose() function step of the link (wich takes two functions as arguments) and you should add callme calls somewhere else ^^

Answer 4

Yeah....I added the initializer now it works

Answer 5

:D

I was trying that first of all, but got error saying that reduce doesn't expect 'initializer' argument ^^

Answer 6

sorry I don't understand your last reply?

In mine, I was implicitly saying 'named' argument... but finally you successed by passing initializer as unnamed argument, wich I have not tried ;P

Answer 7

Yeah forgot to save

Answer 8

I forgot to save the working version.

Answer 9

Oh I see now... no need of your old callme function ^^

Answer 10

Oh...tell me how?

Answer 11

I mean the one wich was expecting arg and function as argument ^^

now your actual callme function is like the compose2 one returned by compose function in the link I had first provided ;P
