I wasn't intending to work on it. I just wanted to fiddle it to see what
happened with my source code generator.

Since the generated code for Oracle is so wrong, I'd have to say the 2nd option
will be a much cleaner result.
For the record, what I've done is:
o Created a test program which when run generates Perl source
o Converted that program into a HTML::Template-style template, with a couple of
loops over table names
<code>
$boilerplate as recommended elsewhere
<tmpl_loop name=package_loop>
package <tmpl_var name=module_name>;
use base 'Base::Object';
__PACKAGE__ -> meta -> table('<tmpl_var name=table_name>');
__PACKAGE__ -> meta -> auto_initialize;
1;
# -----------------------------------------------
</tmpl_loop>
package main;
<tmpl_loop name=module_loop>
print <tmpl_var name=module_name> -> meta -> perl_class_definition
(
braces => 'bsd',
);
print "\n# ===============================================\n\n";
</tmpl_loop>
</code>
o Created another program which feeds all table names into the template and
generates yet another program (YAP) which, when run, outputs a Perl module for
each table. This is the code which needs correction
o So I have iterative :-) but not recursive :-( source-code generation
o Now the plan is to fabricate and edit Rose::DB::Object::Metadata::Auto::Oracle
until it creates the correct output
