Subject: AQ&S Guidance on pragma Elaborate_Body
Date: 1997/04/18
Date: 1997-04-18T00:00:00+00:00 [thread overview]
Message-ID: <528878564wnr@diphi.demon.co.uk> (raw)
In the rationale to Section 8.4.3, Coupling Due to Pragmas, the second
paragraph says:-
"When there is a clear requirement for a recursive dependency, you
should use pragma Elaborate_Body. This situation arises, for example,
when you have a recursive dependency (i.e., package A's body depends on
package B's specification and package B's body depends on package A's
specification)."
The most obvious interpretation of this is that the pragma should appear
in both packages - which will generate an error, probably at link/bind
time.
So is there a meaningful message struggling to get out here? [Perhaps
"a clear requirement" can be replaced by "no requirement", so that a
successful build confirms that no circular package depencies have been
introduced unwittingly.]
[The suspicion of poor authoring/editing is reinforced by the rather
strange wording where X is an example of X.]
