Hello, I was wondering. Are there languages that use only pass-by-reference as its eval strategy? Thank you.

I have a hook system setup... which is working on localhost... I put it live and get an error saying "Warning: Call-time pass-by-reference has been deprecated".
Now, apparently the work around is to remove all "&" from your function calls, ie foo(&$me) to foo($me) and then in foo's function…

instance2 <-new("MyClass",name="Hello2")
array = c(instance1,instance2)
instance1
array
instance1@name="World…

struct MyClass
{
void changeParameter(Parameter &p){ p.setA(-1);}
};
Well, let's fast forward, and imagine I already wrapped those classes, exposing everything…

I was wondering, in java, is it possible to in anyway, simulate pass by reference for an array? Yes, I know the language doesn't support it, but is there anyway I can do it. Say, for example, I want to create a method that reverses the order of all the elements in an array. (I know that this code…
