This has the advantage that , if you happen to know that b has dynamic type b , then you know more about it than if you are doing verification assuming that b has type A. From the point of view of clients , who think they have an object of type A , this works out , and fits in with the general idea of behavioral subtyping . Cover CaptionIn the vertebrate brain , the molecular programs controlling the development of distinct subtypes of neurons are largely unknown . In the second part , we propose a realistic constraint solving algorithm for the case of structural subtyping , which handles the non-standard construct of the constraint language generated by type inference : a form of bounded universal quantification . In the case of structural subtyping , it is not possible to rely on the names of interfaces or the names of the types of the arguments to aid in the disambiguation . The preponderance of women and of paranoid subtype patients seen in late-onset schizophrenia supports this view .
