What is a good way to iterate through struct contents?

What information about a type/class can we get?
You can access non-static member variables with structured bindings. See for instance magic_get/boostPfr https://github.com/apolukhin/magic_get. Structured bindings will only bind to the accessible members (not private). Magic get works by by finding the number of member variables, converting the struct to a tuple (with a function that is specialized for the number of fields), and finally accessing the members through the tuple (supporting indexing and iteration). It does not grant access to the member names, but it is sufficient for some reflection.

A way to determine the number of elements in a structured binding
Libraries like magic_get expose the members of an aggregate class/struct to allow writing generic code for things like pretty printing and serialization without anything special done to the class itself. They often rely on structured bindings for the decomposition (*), but find the number of elements via SFINAE on aggregate initialization, as an aggregate type can be initialized only from as many objects as it has members. It would be nicer if you could SFINAE directly on the structured binding itself, as then the type could have user-defined constructors (which aggregates can't). Unfortunately, this is not possible since structured binding is a statement and not an expression. Unless you're using Clang, where the GNU statement expressions extension allows you to do SFINAE on them, as in here.

Minimum viable declarative GUI in C++
No RTTI required, but the types are required to be aggregates (no constructors defined). It's possible to count the number of members using SFINAE by trying different numbers of inputs to the aggregate constructor using a type that's castable to anything, and then enumerate the members with a similar trick (or use structured binding to pull them out directly). I think he uses magic_get which is the most popular library for this trick.

Call function on each member of struct using preprocessor
take a look at magic_get to get access to all struct members. No idea what your plan is with foo and the preprocessor though.

Reflecting Over Members of an Aggregate
I actually reference it near the bottom of the article under its original name, magic_get! I was disappointed to discover that this library did it a similar way first before me while researching 😅
