Tutorial 4.8 call by value vs reference is confusing

[HelenaSeidel]

Documentation

The part about how arguments are passed in Section 4.8 (by value vs by reference) is written in a confusing way and there is even a footnote admitting to it

IMO an improvement would be along the lines:
Arguments are always passed using call by value. For objects that are passed this value consists of a reference to that object. Which means that mutations to the object are visible outside, reassignments of another reference to the variable inside the function are not. insert example

Hi , I would like to work on this issue if it's not already handled . I think you are talking about the line below right ?

The actual parameters (arguments) to a function call are 
introduced in the local symbol table of the called function when it is called; 
thus, arguments are passed using call by value (where the value is always an object reference,
 not the value of the object).

I would like to work on this documentation improvement. I will prepare a PR to clarify the call by value vs reference explanation in Tutorial 4.8.

Just created something similar and saw your PR just now, it's similar, would be fine by me
