Keynote: C++ Horizons
summary
C++ is set to add reflection-based enum name extraction, compile-time injection for generating wrappers and struct-of-arrays transformations, and hash_append via member splicing to recursively hash members. Pattern matching (inspect) lets code decompose values and build a JSON serializer via reflection and guards. An asynchronous model of senders with stdexec prototype composes sender pipelines, runs on CPU/GPU/distributed schedulers and is shown scaling to ran on 512 GPUs for simulations; a generic parallel inclusive-scan and async network-read examples are implemented and shown working.
