The humble struct. We all use it. We all bump up against its limitations, especially when trying to manipulate it at compile time.

What if I told you that C++20 has enough features that we can meta-program a struct replacement?

Want to have static, compile-time introspection?

Want to add and remove members with compile-time programming?

Want to have type deduction for members?

Want to easily convert from array of structures to structure of arrays (SOA) to optimize cache-friendly traversal?

C++20 allows us to do all these things and more!

No preprocessors, no macros, just standard C++.

Come join me as we explore the magic unleashed by C++20!

I first started programming in C++ at age 14 in 1994 when I cajoled my parents into buying me Visual C++ 1.0 for my birthday. It took a while, but as I learned the language, I decided I really liked C++. I attended the University of Florida and obtained my undergraduate degree in Computer and Information Science. During my undergraduate time, I created and submitted Boost.Tokenizer. I went on to medical school and neurosurgery residency, but decided to do something with a little less scary undefined behavior and returned to programming in C++.
