In Ruby you can assign to a constant as many times as you like. You
will be scolded for it, but it's allowed.

irb(main):001:0> IMA_CONST = "foo"
=> "foo"
irb(main):002:0> IMA_CONST = "bar"
(irb):2: warning: already initialized constant IMA_CONST
=> "bar"
irb(main):003:0> IMA_CONST = "baz"
(irb):3: warning: already initialized constant IMA_CONST
=> "baz"
irb(main):004:0> IMA_CONST
=> "baz"
