For reference, some associated Policy Notes (you don't need to visit these links yet):
Mathematica: Webel ADT pseudo classes: POLICY: The expression '$$' is reserved as the primary named parameter for the defining pattern of all ADT classes that extend the universal base 'ADT' class.
Mathematica: Webel ADT pseudo classes: NAMING CONVENTION: An UpValue that can be invoked on an ADT accepting its unique 'signature' pattern as (at least) 1st argument is called an 'ADT-Method'. They are NOT methods in the general object-oriented sense!
Beware that:
Mathematica: Webel ADT pseudo classes: The ADT⊙get method may be used to access the '$$' wrapped primary. This is intended for development and testing purposes only (not for regular use by clients) since it BREAKS ENCAPSULATION!

Notes
[EXPLANATION]{INFORMATIVE} Mathematica: Webel ADT: The term 'Abstract Data Types (ADT)' is used informally (the Webel ADTs do not always adhere to strict definitions of ADTs). Please just think of it here as meaning a strong type or stateless "pseudo class".
[POLICY]{STRICT} Mathematica: Webel ADT pseudo classes: POLICY: The expression '$$' is reserved as the primary named parameter for the defining pattern of all ADT classes that extend the universal base 'ADT' class.
[POLICY]{STRICT} Mathematica: Webel ADT pseudo classes: The ADT⊙get method may be used to access the '$$' wrapped primary. This is intended for development and testing purposes only (not for regular use by clients) since it BREAKS ENCAPSULATION!
[CONVENTION, NAMING]{STRICT} Mathematica: Webel ADT pseudo classes: NAMING CONVENTION: An UpValue that can be invoked on an ADT accepting its unique 'signature' pattern as (at least) 1st argument is called an 'ADT-Method'. They are NOT methods in the general object-oriented sense!
