DBIx::Class::MooseColumns - Lets you write DBIC add_column() definitions
    as attribute options

    This is ALPHA SOFTWARE. Use at your own risk. Features may change.

    This module allows you to put the arguments to "add_column" in
    DBIx::Class::ResultSource right into your attribute definitions and will
    automatically call it when it finds an "add_column" attribute option. It
    also replaces the DBIx::Class-generated accessor methods (these are
    Class::Accessor::Grouped-generated accessor methods under the hood) with
    the Moose-generated accessor methods so that you can use more of the
    wonderful powers of Moose (eg. type constraints, triggers, ...).

    *Note:* "__PACKAGE__->table(...)" must go before the "has" stanzas (the
    "table" in DBIx::Class::ResultSource is magic and does much more than
    setting the table name, thus the "__PACKAGE__->add_column(...)" calls
    that the "has" triggers won't work before that).

    *Note:* "__PACKAGE__->set_primary_key(...)" and
    "__PACKAGE__->add_unique_constraint(...)" calls must go after the "has"
    stanzas (since they depend on the referred columns being registered via
    "__PACKAGE__->add_column(...)" and that call is done when the "has"

    *   convert the test harness to something sane - consider Fennec?

    *   delay ->add_column() calls until right after the ->table() call
        (collect the args and run them in an after method modifier of
        'table', possibly batched in a single ->add_columns() call)
