Quite agree. It is hard to see how you could do database support
without them, with out using truly ridiculous levels of overloading. I
can't see any (sensible) way of doing a key search on a complex key
without passing an array of variants.
On the the other hand, I never use them if I can avoid them. For
example, I would always typecast a TField to a specific field type and
use the value property rather than use the AsVariant property of a
generic TField if I knew the Field type.
