Hi Bulat,

I am using Ruby v 1.6.7 (which is called the "stable version" at
www.ruby-lang.org).

First, I think in array.c "len" is really of type long (4 bytes in my
machine).

Second, if you use "Array.new(n)" (as for tuple also we need to know the 
exact size when we create it), then although initially Ruby allocs 16
elements, it will be resized immediately to exactly n elements.  So I
guess using tuple will only save memory of 4 bytes per array (assuming the
underlying pointer handle is the same for array and tuple).

Regards,

Bill
