I typed that wrong.
{ 'union': 'Flat', 'base': 'Base', 'discriminator': 'type',
'data': { 'branch1': 'NamedTypeOkay',
'branch2': { 'anon-type-okay': 'str' },
'branch3': { 'okay': str', 'bad-nesting': { 'i': 'int' } } } }
and where anonymous types are still okay is that if we add long-hand for
expressing optional types, or otherwise use a dict in place of a type,
we can do:
{ 'union': 'Flat', 'base': 'Base', 'discriminator': 'type',
'data': { 'branch1': 'NamedTypeOkay',
'branch2': { 'anon-type-okay': { 'type': 'str',
'optional': true } } } }
,
That is, there is a difference between the dictionary expressing an
anonymous type, and the dictionary expressing additional attributes
belonging to a member of a struct.
