Well, no, not really. The accessor method is called within load() in
order to determine if a column has a defined value. The accessor
method then returns the default value if the actual value is undef.
Nothing interesting related to this happens in new().

It sort of is (see above) depending on your definition of "delayed"
and "populated." :)

What would load() do with that information? Disregard such column
values? I know I've had classes where I *want* a default value to
contribute to a unique key just the same as if it was set manually, so
there's no obvious, single answer for what to do in that situation.
Allowing a key name to be specified as a parameter to the load() call
is a better idea, I think. (That'd require people to give their
unique keys nice/sensible/memorable names, of course.)
