This Milestone is here to group issues, and doesn't mean I have short-term plans to work on this.

The issues in this Milestone are not a complete list of work to be done to support Catalyst.

At the very least:

• Work with CPython project to create a Catalyst build of CPython
• Update metadata tooling to support Catalyst
• Update test suite to support Catalyst (in particular "min_os_level" and "min_sdk_level")
• Look for differences in headers between the macOS en Catalyst SDKs (in particular for enums and type definitions)
• Add an extendable "available" function to replace "objc.mac_available"
