Aliased as ==

Examples

iex> equivalent?(1, 2)
false

iex> import Kernel, except: [==: 2, !=: 2]
...> %{a: 1} == %{a: 1, b: 2}
false

equivalent?(%Maybe.Just{just: 42}, %Maybe.Nothing{})
#=> false

Equivalence not equality

baby_harry = %Wizard{name: "Harry Potter", age: 10}
old_harry  = %Wizard{name: "Harry Potter", age: 17}

def chosen_one?(some_wizard), do: equivalent?(baby_harry, some_wizard)

chosen_one?(old_harry)
#=> true
