Reflection without Reflection TS
summary
A catalogue of concrete techniques and limits appears: template specialization and SFINAE check pointer/array/polymorphic properties; dynamic_cast to void for a polymorphism test works but relies on standard corner cases; enum names come from __PRETTY_FUNCTION__/SourceLocation so it is implementation‑defined and MagicEnum wraps it; member counting and types use aggregate‑init recursion to count members and an implicit‑conversion any to deduce types* and it works but is fragile; clang trunk exposes dump_struct for names at compile time.
