Certainly, but this is something where, in my opinion, the aims of SOCI
the successful database access C++ open source library and of Boost.SQL
the library that will be included in the Library TR 3 and C++1x diverge.

Certainly! There are several Boost libraries which I wouldn't want to
include in a future standard, yet I find very useful: Spirit is the
first that comes to my mind.

What is important in my opinion is to layer the components very
carefully and to tackle them one by one. This reminds me of another
reason why I want Boost.SQL to be limited to basic SQL access; while the
design for this part is sort of given and I do not expect difficulties
in gaining acceptance, everybody (me included!) have their own pet idea
about what should go above it.
