In the future, please to not multi-post.  Instead, put each of the
intended newsgroups into the 'Newsgroups' header.  That way,
replies are not duplicated and threads are not disjoint.

Your query has already been answered, redundantly, in at
least two of the newsgroups you multi-posted to.

Followups set accordingly.

I do it for clarity. While it takes a compiler a mere fraction of a
millisecond to resolve the scope of an unqualified function call, it is
often much more tedious for humans.
