You missed a few features of Text::xSV
It wasn't my intention to make a full comparison of the features, only of the CSV parsing. Like Text::xSV, AnyData and the DBDs also have many options for handling the resulting data structures, it would take a much lengthier meditation to compare all of those.
Adding a few features shouldn't be difficult.
Those features may or may not be worthwhile in Text::xSV. I didn't intend the minus signs in the chart to necessarily indicate something the modules should support. Then again if
Tilly does add the user-defined features, I can use Text::xSV as a backend for DBD::AnyData so that there would be a DBI/SQL interface to his excellent module.
