FWIW, this is an Ada-83 trick used by a small but significant group: The
author doesn't want to "use" SI, but wants direct visibility to its
operators; therefore, he puts the operators in a subpackage, and uses
it: "use SI.Ops;".

In Ada, one can achieve the same effect without the subpackage with "use
type".
