The ByRef part can also be optional. Therefore, if no argument is given and no global variable exists, then a local variable is created.

Basically that is what I said in a nutshell :D

I do not support this behavior. I support the idea of an optional ByRef parameter. But I do not support the second part of the idea proposed here - that a local variable will be created.

what i think that supposed to happen is that the variable will be ignored completely

Why do you think that it is better than my suggestion of creating a Local variable? :)

If you define a default value for a function parameter, a variable has to be created. If you pass a literal value to a ByRef parameter, then either you create a local variable or you throw an error: you shouldn't just ignore it. There are several advantages to allowing literals to be passed ByRef to function parameters with (or without) defined default values: the concept being flexible and robust. On the other hand, not allowing it seems to offer little advantage.

Such a change is unlikely to be script breaking, but it might produce some unexpected side effects - fixing scripts that are currently broken. :idiot:
