What you write belowe seems very sane. But I think that my keyevent
queue is still needed? (but to fix a different problem)

| +inline flags operator|(flags const f, flags const g) 
| +{
| +     int const intf(static_cast<int>(f));
| +     int const intg(static_cast<int>(g));
| +     return static_cast<flags>(intf | intg);
| +}e

Is the temporary insts needed?


inline flags operator|(flags const f, flags const g)
{
        return static_cast<flags>(f | g);
}

should be enough.

enum -> int  // implicit ok
int -> enum  // implicit not ok
