Thanks HTH, but no success, I'm afraid.

The entire query is:

select object_name from user_objects where object_type like 'PACKAGE' and object_name like '%\_T\_%';

This returns no results at all, but I can see loads of packages containing the '_T_' when I do the select:

select object_name from user_objects where object_type like 'PACKAGE' and object_name like '%_T_%';

This returns all objects containing the letter 'T', of course.
