+If C<exception_action> is set for this class/object, L</throw_exception>
+will prefer to call this code reference with the exception as an argument,
+rather than its normal <croak> action.
+
+Your subroutine should probably just wrap the error in the exception
+object/class of your choosing and rethrow. If, against all sage advice,
+you'd like your C<exception_action> to suppress a particular exception
+completely, simply have it return true.
+
+Example:
+
+ package My::Schema;
+ use base qw/DBIx::Class::Schema/;
+ use My::ExceptionClass;
+ __PACKAGE__->exception_action(sub { My::ExceptionClass->throw(@_) });
+ __PACKAGE__->load_classes;
+
+ # or:
+ my $schema_obj = My::Schema->connect( .... );
+ $schema_obj->exception_action(sub { My::ExceptionClass->throw(@_) });
+
+ # suppress all exceptions, like a moron:
+ $schema_obj->exception_action(sub { 1 });
