Ok, let it be dynamic_any. Here is only one mirror problem. Three words in 
dynamic_any_cast while all others known (to me) casts consist of two words: 
static_cast, reinterpret_cast, dynamic_cast, any_cast, lexical_cast, 
numeric_cast and so on.
I'd like to get responces about operators == and != for dynamic_any and 
using of std::set<dynamic_any> and std::map<dynamic_any, value_type>. How 
often they were simulated and how successully? Your responces can help to 
understand real need of these features.
