5. SSQLS structures should derive from a common base class. This let
you put some useful common code in the MySQL++ library itself, but more
importantly, it would let you make methods like Query::insert() into
regular methods instead of templates.
Give a more detailed description (example), please.
What else needs to be explained? It would be useful if all SSQLSes
derived from a common base class that lives in the MySQL++ library.
There's nothing more complicated than that to it.
I mean "what do you think about interface of that common base class" :)
