In both styles, same key words are automatically merged when parsing it
at boot time. So you can append similar trees or key-values.
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
