Hmmm ... can you do that in this case? Data::FormValidator::Constraints::Upload *requires* File::MMagic within the valid_file_format method -- so there's nothing in the symbol table you can manipulate beforehand.

In this particular case, I think a subclass is the way to go - derive from Data::FormValidator::Constraints::Upload and just override the valid_file_format method.
