I'd like to mention we are speaking not about but some bugs but
about known features of CINT.
Since CINT knows how the object was created it may treat either
"character" (I mean "." or "->") the proper way according the real
definition of the object /pointer (By the way it would be better all
C++ compiler make users free of this headache too).
I'd like to mention that there is difference between CINT language
and C++ (scope rules, object / pointers id's etc) otherwise
C++ is useless as an "interactive" script language.
