Scenarios

Extension mechanism: Composition vs Inheritance

Kinds of Configuration

• Lots of statically computed/defined value, a few inputs
• No statically computed/defined value, a few inputs

Considerations: To allow or not allow extension

• allow extension: actually extending a module
• not allow exntension: using a module (prevent mistyping a field name etc.)

Because we are using "merge" to serve two purposes:

• defining new module by extending an existing module
• using a module (filling in inputs)
