This package implements the following methods.

=cut

=head2 try

  try(Str | CodeRef $method) : Object

The try method takes a method name or coderef and returns a
L<Data::Object::Try> object with the current object passed as the invocant
which means that C<try> and C<finally> callbacks will receive that as the first
argument.

=head2 result

  result(Any @args) : Any

The result method executes the try/catch/default/finally logic and returns
either 1) the return value from the successfully tried operation 2) the return
value from the successfully matched catch condition if an exception was thrown
3) the return value from the default catch condition if an exception was thrown
and no catch condition matched. When invoked, the C<try> and C<finally>
callbacks will received an C<invocant> if one was provided to the constructor,
the default C<arguments> if any were provided to the constructor, and whatever
arguments were passed directly to this method.
