		Same-key Values
		---------------

		It is prohibited that two or more values or arrays share a same-key.
		For example,::

		foo = bar, baz
		foo = qux # !ERROR! we can not re-define same key

		If you want to append the value to existing key as an array member,
		you can use ``+=`` operator. For example::

		foo = bar, baz
		foo += qux

		In this case, the key ``foo`` has ``bar``, ``baz`` and ``qux``.

		However, a sub-key and a value can not co-exist under a parent key.
		For example, following config is NOT allowed.::

		foo = value1
		foo.bar = value2 # !ERROR! subkey "bar" and value "value1" can NOT co-exist
