The Perl database independent interface - DBI - does not take much advantage of Perl's context sensitivity. This is the situation where a Perl subroutine knows whether the caller wants a single scalar value or a list of them to be returned. . DBIx::ContextualFetch is a sub-class of DBI which redefines some of the various fetch methods to fix this oversight. It also adds a few new methods for convenience (though not necessarily efficiency). Much of this code was originally part of the IMA::DBI Perl module (libima-dbi-perl package).
