You'd have to follow the language mapping, which would be

   MyStruct([[],[],...],0)

in this case, or

   MyStruct([[DictEntry("foo",aval)],[]],0)

in the case of ([{"foo",aval},{}],0). If you really need arbitrary
value types for the dictionary, you'd need to create it using the Any
interface, i.e.

   aval = CORBA.Any(CORBA.TC_long,42)

If you go for IDL structures, I'd really recommend to declare a more
specific type for the dictionary values.

If you are using ILU, you may consider activating the ILU extension,
where ILU would accept Python dictionaries for the above Dictionary
type: With this extension, ILU maps sequences of two-field structures
to dictionaries, if the field names are key and <?>.
