First off, I think this is better than DBIC::Validation. It is a
better fit to the ResultSet/Row separation that DBIC is all about.
That said, there's a few things that I'd like to see be done:
1) With one setting, I should be able to turn on validation for all my
columns that have a type set for them. So, if I have a column that is
an integer, that should just turn on for me.
2) I should be able to chain validations. So, something like
"validation => [ 'foo', 'bar' ]". Look at how Moose does this.
3) Different DBMSes have different types. So, maybe producer-specific
validations would be helpful (q.v. #1).
This is also starting to get very very close to custom types. There's
been discussion of this for 0.09. I think getting you involved would
be very helpful.
