[Catalyst] YAML config embedded path_to mysql_read_default_file

[apv]

So, I would like to use a mysql connection file instead of putting  
the password and user in the config file. Can I get a path_to to work  
with this? I did Google and check the lists but couldn't find an  
answer. Where the "__HERE__" is is where the mysql_read_default_file= 
(path_to) goes.

   Model::DBIC:
     schema_class: MyApp::Schema::DBIC
     connect_info:
        - "dbi:mysql:opendevil;__HERE__;"
        - ~
        - ~

Thanks!
