Allocate it where?

Subject: Returning functions from other functions, and thinking about the stack, the heap, and reference types.

Notes

This episode, we look at returning functions from other functions, and as part of that discuss some basics about the stack and the heap—and why we need to care about them for returning functions.

The functions themselves are not especially interesting; they just show you the basic form you use to return functions from other functions, and how to then use them in another function. You’ll want to take a detailed look instead at the documentation for each (or just read the source!), because that’s where the meat of the discussion in this week’s code is.
