Hi Stephane,


thanks for linking the upcoming lesson. I'll have a look. :-D


Best, Steffen

BTW to me when a block needs too many arguments it feels like that an object has to be born :)
With an object I can just sent or not a given extra argument. 


Now I do not know enough your specific context but what I learned is that complex blocks are difficult to follow, manipulate…
so I keep block as simple as possible and else I create little objects.




This is a little lectures from a super cool forthcoming mooc

Hi!

I want to evaluate a block an argument 'arg1' and additional n arguments
given in an array 'args'. The following code does the trick:

  block valueWithArguments: (Array with: arg1) , args.

Is there a way to do this without the overhead of creating a new Array?
(How) Can I add additional #value:value:[...] methods to BlockClosure that
evaluate the block with n arguments directly without falling back to
#valueWithArguments: ? If yes, what's the maximum?

Cheers!
Steffen
