Jordan Bedwell is correct. Ruby's constants are /meant/ to be not changed, but
you can define a constant and change its value later. Ruby will produce a
warning 'already initialized constant'
Also note that your constant's internal representation can be changed without
triggering the warning.
1.9.3p374 :001 > Const = 'a'
=> "a"
1.9.3p374 :002 > Const = 'b'
(irb):2: warning: already initialized constant Const
=> "b"
1.9.3p374 :003 > Const = {a: 'a'}
(irb):3: warning: already initialized constant Const
=> {:a=>"a"}
1.9.3p374 :005 > Const[:a] = 'b'
=> "b"
