MooseX::TransactionalMethods - Syntax sugar for transactional methods

  package Foo::Bar;
  use MooseX::TransactionalMethods; # includes Moose
  
  has schema => (is => 'ro');
  
  transactional foo => sub {
     # this is going to happen inside a transaction
  };

This method exports the "transactional" declarator that will enclose the method in a txn_do call.

When you declare with only the name and the coderef, the wrapper will call 'schema' on your class to fetch the schema object on which it will call txn_do to enclose your coderef.
When you declare sending the schema object, it will store it in the method metaclass and use it directly without any calls to this object.

NOTE THAT MIXING DECLARTIONS WITH SCHEMA AND WITHOUT SCHEMA WILL LEAD TO PAINFULL CONFUSION SINCE THE WRAPPING IS SPECIFIC TO THAT CLASS AND THE BEHAVIOR IS NOT MODIFIED WHEN YOU OVERRIDE THE METHOD. PREFER USING THE DYNAMIC DECLARATOR WHEN POSSIBLE.
