HI
@kaz. thanks. I will check the %union later
I'like to use the smart pointers ( std::unique_ptr) , but somehow I got 
some compiler errors.

here are some details:
e.g:

using PROG_PTR = std::unique_ptr<PROG>;

"using" is now a full-blown alternative for typedef?

I don't keep up closely with the C++ standard.

The old-fashioned way is:

 typedef std::unique_ptr<PROG> PROG_PTR;

The "using" that I remember was purely for bringing long, qualified 
names into the current scope as short names, not for creating alias 
names for types.

 using foo::bar::baz; // the unqualified name baz can now be used in 
this scope
