any?(t(), (element() -> as_boolean(term()))) :: boolean()
Returns true if fun.(element) is truthy for at least one element in enumerable.

of fun returns a truthy value (neither false nor nil) iteration stops
immediately and true is returned. In all other cases false is returned.
Examples
iex> Enum.any?([2, 4, 6], fn x -> rem(x, 2) == 1 end)
false
iex> Enum.any?([2, 3, 4], fn x -> rem(x, 2) == 1 end)
true
iex> Enum.any?([], fn x -> x > 0 end)
