L<around|Moo/around> a read-only accessor to make it L<carp|Carp/carp>
instead of die when passed an argument.
+=head2 batch_alter_table_statements
+
+Takes diff and argument hashes as passed to
+L<batch_alter_table|SQL::Translator::Diff/batch_alter_table($table, $hash) (optional)>
+and an optional list of producer functions to call on the calling package.
+Returns the list of statements returned by the producer functions.
+
+If no producer functions are specified, the following functions in the
+calling package are called:
+
+=over
+
+=item 1. rename_table
+
+=item 2. alter_drop_constraint
+
+=item 3. alter_drop_index
+
+=item 4. drop_field

+
+=item 8. alter_create_constraint

+
+=back
+
+If the corresponding array in the hash has any elements, but the
+caller doesn't implement that function, an exception is thrown.
