inferred type arguments.
Otherwise, type inference fails and the program is invalid.

<p>
Type inference uses the type relationships between pairs of types for inference:
For instance, a function argument must be <a href="#Assignability">assignable</a>
to its respective function parameter; this establishes a relationship between the
type of the argument and the type of the parameter.

- Introduced the Node Declared Features capability (alpha), which includes:
  - A new `Node.Status.DeclaredFeatures` field for publishing node-specific features.
  - A `component-helpers` library for feature registration and inference.
  - A `NodeDeclaredFeatures` scheduler plugin to match pods with nodes that provide required features.
