The Sequel::BasicObject class is just like the default
BasicObject class, except that missing constants are resolved
in Object. This allows the virtual row support to work with
classes without prefixing them with ::, such as:
DB[:bonds].where{maturity_date > Time.now}
Lookup missing constants in ::Object
