Lecture 11. Closures-. ish. Java & . C. Dan Grossman. Fall 2011. Higher-order programming. Higher-order programming, e.g., with . map. and . filter. , is great. Language support for closures makes it very pleasant. Lecture 12. Modules. Dan Grossman. Fall 2011. Modules. For larger programs, one “top-level” sequence of bindings is poor. Especially because a binding can use . all. earlier (non-shadowed) bindings. Lecture 27. Generics vs. Subtyping; Bounded Polymorphism. Dan Grossman. Fall 2011. Today. Compare . generics and . subtyping. What each is good for. Combine generics and subtyping to get even more . benefit. Lecture 9. Function-Closure Idioms. Dan Grossman. Fall 2011. More idioms. We know the rule for lexical scope and function closures. Now what is it good for. A partial but wide-ranging list:. Pass functions with private data to iterators: Done. Chapter One. Modern Programming Languages, 2nd ed. . 1. Outline. What makes programming languages an interesting subject? . The amazing variety. The odd controversies. The intriguing evolution. The connection to programming practice. Lecture 25. Subtyping for OOP;. Comparing/Combining Generics and Subtyping . Dan Grossman. Winter 2013. Now…. Use what we learned about subtyping for records and functions to understand subtyping for class-based OOP. Lecture . 9. Function-Closure Idioms. Zach Tatlock. Winter 2018. More idioms. We know the rule for lexical scope and function closures. Now what is it good for. A partial but wide-ranging list:. Pass functions with private data to iterators: Done. Lecture 14. Thunks. , Laziness, Streams, . Memoization. Dan Grossman. Spring . 2017. Delayed evaluation. For each language construct, the semantics specifies when . subexpressions. get evaluated.
