alt Hacker News>C++26 is also a joke imho.
C++26 will allow billions of lines of pointless serialization boilerplate to finally be deleted, adding the basic reflection functionality that most other languages have had for decades.

Reflection is a joke. De/serializing arbitrary C++ structs is ill-defined. When you need serialization, even lots of it (e.g. silly JSON), I think you're better off writing your own framework where you can be clear about data formats and transformation rules.
Yes, C++26 reflection is nice, but also extremely complex to understand and use well. The rest of C++26 is the usual series of too-little-too-late additions. Meanwhile I’m still waiting for pattern matching to become a thing (a proposal has been discussed for ages)
I can't think of a time where using reflection for serialisation hasn't come back to bite me.
I'm not sure C++26 reflection is sufficiently well-baked to actually allow it to be used for serialization boilerplate in codebases. What matters is not what the standard says, but what the compilers implement, and the compiler implementers I know have been kvetching about how problematic reflection is, to the point that it may never be turned on by default.
