Why would I write a parser that almost-but-not-quite matches the compiler's own parser, when I could just use the compiler's parser directly? I don't want to write a parser, and I especially don't want to debug weird corner cases where my implementation diverges somehow. I just want to write some code that goes like, for each field in T, do X.

C++ metaprogramming is bad, but the problem there is the C++ part, not the metaprogramming-in-the-language part.

Cause its dead simple. Shell out, run a quick sed or something, then compile it in. It is quite amazing what 'magic meta' stuff you can do with that shit. Meanwhile 10 years in we are finally getting reflection.....

C++ is often cross compiled from mostly identical sources. Here is an example from Zig [1] that explains why it is not that simple.
