Yes, euml uses another name (which is an instance of an internal type,
and not a type definition like no_exception_thrown but I disgress).

Great!

Yes of course. The method process_any_event is simply there for the
favor_compile_time policy (to allow compiling submachines on different
cores). So without rtti, all you lose is the possibility to trade
runtime speed in exchange for a better compile time, which is in your
case probably unimportant as you seem to be more interested in
performance.
