Mapping Python to CORBA

[Andrew MacKeith]

Is there any standard for mapping standard Python
types to CORBA IDL types?

I have read the CORBA Python Language Mapping spec,
which describes how CORBA IDL types are mapped to 
standard Python types.

The reverse mapping is not documented.  In some cases
it is clear (such as string -> string, int -> long,
float -> double), but for others (dictionary, list) it 
looks as if I have to write my own interface.
