[gtkmm] struct ustring::SequenceToString<In,char> : public std::string

["Hopfes, Harald" <Harald Hopfes Hopfes sysde eads net>]

Hi!

I am new to gtkmm,

but as you say at the beginning of file glib/glibmm/ustring.h
std::string is intended to be a final class, but
ustring::SequenceToString<In,char> is a child of std::string??

Is that correct?
