For the interested reader, there is an entire book written on the topic of =
Pimpl (before it was called Pimpl):
John Lakos's _Large Scale C++ Software Design_ (1995).

Oh really!  Read Lakos's book then.  All 852 pages of it effectively say:  =
C++ is almost an unmitigated disaster in controlling physical dependencies =
unless you walk the very narrow path that he lays out.  852 pages.  Eight h=
undred fifty-two.  When a language has a problem that needs 852 pages to ex=
plain and straighten out, methinks it actually might have an actual problem=
 (or whole tangled nest of problems) in that vicinity.

By comparison, in Ada's entire history spanning 5 decades, no one needed to=
 write an analogous 852-page tome on that topic.
