The reasen this can't be allowed is very simply: Look at this:

ArrayList s = new ArrayList();
ArrayList t = s; // Does not compile, but asume that it would.

t.addElement(new Float(10.5)); // Now we have added a float to a list which can ONLY contain integers. Not good.

Integer i= s.elementAt(0); // Class cast exception.

Allowing t=s would ruin the entire "You are sure your collection only can contain what it say it contains, and we check that at compile time"

What do you mean it does not compile??? Of course it compiles. What are you talking about? Did you mis-type?

Since when did you DEFINE that the arrayList could only contain integers??? I see no such constraint.

i = [1, 2, 3] # array of integer
n = i # array of number

Seems like other languages support it ...
