Subject: multiple array declaration using one Object::new call

Hello,

I apologize if this has been covered, but I searched and could not find
anything resembling this issue.  I am fairly new to Ruby and I'm having
a strange problem that may be my misunderstanding of how Ruby works.

I am trying to declare multiple arrays on one line, like such:

array1, array2, array = Array::new()

What happens is that the arrays are all nil and [seemingly] immutable.

When I declare each array individually, like such:

array1 = Array::new()
array2 = Array:new()
array3 = Array::new()

...the arrays are not nil and mutable (as verified with irb).

When I do this with a set of strings, like such:

str1, str2, str3 = String::new()

...str1 is not nil, but str2 and str 3 are nil.

Can someone shed some light on what I'm misunderstanding, and perhaps
guide me to a good source on proper object declarations?

Thanks!
Andy
