Discuss the role of function objects in metaprogramming and code generation tasks, especially in compile-time optimizations.

Dynamic Versus Stack Allocated Memory Describe by example and words the difference between dynamic and stack allocated memory, specifically arrays. How they are created and destroyed, and describe their scope. Are there any limitations with either memory types? Lastly, has modern C++ provided any new features (hint: standard template library data types) to alleviate problems associated with dynamic and/or stack allocated memory?

Discuss the concept of operator chaining in languages like Python and JavaScript. How does it simplify code and improve readability?

To commence, may we present a succinct summary of the compiler, followed by a discussion of advantageous pointers regarding testability?

Define a Haskell data type to represent λ-terms. Give the data type definitions and show how you can represent the λ-term λxf.fx using your data type.

In the context of JavaScript, discuss the significance of callback functions and how they can be seen as function objects.

How do function objects support meta-programming techniques in languages that allow runtime code modification?
