[Bug]: Namespace seemingly has no way to get interspersed type members of different kinds in source code order

[TomerAberbach]

Describe the bug

For example, if I have:

scalar Scalar1 is extends string;

model Model1 {}

scalar Scalar2 is extends string;

model Model2 {}

Then there's seemingly no way to get an array of Type objects from the Namespace that gives me the scalars and models in the right interspersed order. I can get the scalars in order (via namespace.scalars) and the models in order (via namespace.models), but I have no way to know how the scalars and models were placed relative to each other.

The same applies to all other kinds (e.g. unions, nested namespaces, decorator declarations, etc.). Ideally I could do namespace.types and get the list of top-level types so I can emit generated code that reflects the order of types in the TypeSpec file.

Maybe there is a way and I haven't found it. If that's the case, then maybe it should be more obvious.

Reproduction

See above.
