Does __PACKAGE__->config merge the local config with the global config 
before stuffing the values into %$self?

In other words, what's the point of doing

__PACKAGE__->config(foo => 'bar');

in the model instead of just doing

$self->{'foo'} = 'bar'

given that I see modules doing

	SomeOtherThing->new(%$self)
