Hi all,
I'm new here on the list (checking things out from the Class::DBI camp
and I like what I am seeing so far)
As for the syntax above, I think it could be potentially confusing,
since a . is also used to separate a table name/alias from a column
(ie vendor.name or t2.name). I think it would be clearer if a
different symbol was used.

I like that better.

Here are a few other options:
require_objects => [ 'vendor..addresses..state' ]);
require_objects => [ 'vendor^addresses^state' ]);
require_objects => [ 'vendor&addresses&state' ]);
Or to make it a bit more visually distinctive, maybe allow some
optional whitespace:
require_objects => [ 'vendor & addresses & state' ]);
