C's static equivalent

Hi!

Is there something similar to C’s static keyword?
I want a single function, which has to access and modify a permanent
variable. Any solution without bundling the function to a class?

Use a closure

Could you be more verbose? Eg. how to print out how many times a
function was called.

end

class Object

Woof. Thx. It works, but it’s a bit too obscure hacking for a damned
easy counter, isn’t it?

It would be worthwhile for all of us to
learn French in order to learn more of
your wisdom. :slight_smile:
