I'm not really sure you're understanding what was said.
Line 2:
  X = A.freeze
Does nothing except assignment.
10.freeze does nothing. That's what A.freeze actually does.
Assignment changes the reference for a particular variable.
  x = "foo"  a = x  x.gsub(/foo/, "bar")  a # -> "bar"
  x = "foo"  a = x  x = "bar"  a # -> "foo"
This is true whether you're dealing with variables or constants.
