SCRPT — Default-initialization for structs/unions/arrays/user exceptions/valuetypes

In the CORBA Scripting Language Specification v1.0 (OMG TC Document formal/01-06-05),
creating a struct, union, array, user exception or valuetype required to provide
a value for each field.

e.g. Section 3.6.3 "Structure Values" page 3-8:

"The creation of an IDL structure value is achieved by the calling notation
(IDLType(field1,...,fieldn)). The interpreter checks if the number of
given values is equal to the number of the expected IDL fields..."

Ditto in sections 3.7.3 page 3-9, 3.10.3 page 3-15, 3.11.6 page 3-20,
and 3.14.3 page 3-30.

For complex structs, unions, arrays, user exceptions and valuetypes,
Chris Oliver (coliver@mminternet.com) think it would be much more user-friendly
to always allow the "constructor" to be optionally called with zero arguments
which would result in default-initialization of the complex value.
The user can then incrementally fill out the contents of complex values,
for example:

nc = CosNaming.NameComponent()
nc.id = "a"
nc.kind = "b"

Since DynamicAny::DynAny in CORBA 2.3 provides default-initialization,
this requires no extra effort for the implementor.
