It "doesn't appeal" to the OP?  Nor to me.  Not sure I can put my finger 
on it, but if I were the maintainer of GThing, I'd consider its 
specification to be complete without this method.  It doesn't increase 
the value of the class as an abstraction.  Adding it would certainly 
just be a convenience for the caller.  It solves a problem generated by 
the design of the call site, not the design of the class's contract.  
The caller can write his own routine as necessary.
