I am currently upgrading some old modules to V10 and have run into a problem.  Some of the field names begin with a number i.e. 855_test.  I have tried creating this field using the following and each produced an error:

855_test = fields.Many2one ('res.company')       #Syntax error

'855_test' = fields.Many2one ('res.company')      #cant assign to a literal

In the old API it was written like this and worked fine but obviously does not work with the new API:

_columns{

     '855_test': fields.many2one ('res.company'),

}

Does anyone know of a way to get these fields created in the V10 API?  I feel like its something simple I'm missing.

Thanks
