1. A computer-implemented method of processing a textual tag and a textual complement to provide type-safe assignment in an application-specific data structure, comprising the steps configured to execute by a processor: creating a predicator specialization, said predicator specialization specializing a generic predicator, and said predicator specialization having said textual tag and said textual complement; applying to said predicator specialization, a specific target, said specific target included in said application-specific data structure, and said specific target an instance of a first object-oriented class; creating a promissary reference, said promissary reference having said specific target, said textual tag, and said textual complement; storing said promissary reference as a promissary reference base in a depository, said promissary reference base generalizing said promissary reference, and said promissary reference base having access to said textual complement; creating a specific object, said specific object included in said application-specific data structure, said specific object an instance of a second object-oriented class, said second object-oriented class not necessarily distinct from said first object-oriented class, and said specific object associated with said textual complement; storing said specific object, as a genetic object, said genetic object resolvable according to said textual complement; retrieving said promissary reference base from said depository; resolving said textual complement from said promissory reference base to said generic object; dispatching a generic promissary dispatch to said genetic object, said promissary dispatch providing said promissary reference base, and said generic promissaryldispatch specializing to a specialized promissary dispatch to said specific object; dispatching a generic promissary acceptor operation to said promissary reference base, said generic promissary acceptor operation providing said specific object, and said generic promissary acceptor operation specializing to a specific promissary acceptor operation to said promissary reference; and accepting in said specific promissary acceptor operation, said type-safe assignment of said specific-object to said specific target of said promissary reference.
