Make Agents Yourself

Enable to replace a component at runtime with another implementation.

Use the type of component as the basis of it.

Needs to define how to express replacement:

• Using a port as before from another component
• Available when implementing the port to replace subcomponents only (better!)

Needs to define how to implement replacement:

• create a new component
• change the implementation of the existing component
