Pack named

Wraps a structured value into its corresponding named type, converting a raw record or tuple into a strongly typed alias.

Use this when

• You have the inner representation of a named type and need to emit it as the named type itself.
• You are reconstructing a domain type (e.g. BoundingBox) from its component parts.
• You are bridging raw output from a generic component into a typed downstream consumer.

What it does

Takes the underlying representation of a named type and emits the named type. Input {class: DetectedClass, rectangle: Rectangle<Double>} becomes BoundingBox if that named type is defined with the same inner structure.

Inputs

Type	Description
a	Underlying representation of the named type.

Outputs

Type	Description
Named a	The wrapped, named-type version of the input.

Parameters

This transformation takes no parameters. The target named type is inferred from the downstream connection.

Works best with

• Unpack named — natural inverse.
• Components that compose raw records and need to re-emit them as a domain type.

Caveats

• The inner representation must match the named type's definition exactly — field names, types, and order for records; element types and positions for tuples.
• There is no runtime type coercion — only named-type wrapping.
