The current proposal document P0707R1 contains the current "what it is" writeup with technical overview.
The header contains the things you can query (e.g., .variables(), .member_variables()) and do (e.g., make_pure_virtual()).
The header contains the compiler.error(), .require(), and .debug().
The primary set of examples is in /tools/libcppx/examples.
Additionally, the P0707 paper contains the following examples linked to the online live compiler:
- interface
- base_class
- value (regular type)
- plain_struct
