<b>A.</b> As an aid to writing test cases and debugging displays. One of the
progenitors had use_count(), and it was useful in tracking down bugs in a
complex project that turned out to have cyclic-dependencies.</p>
<p><b>Q.</b> Why doesn't <b>shared_ptr</b> specify complexity requirements?<br>
<b>A.</b> Because complexity limit implementors and complicate the specification without apparent benefit to
<b>shared_ptr</b> users. For example, error-checking implementations might become non-conforming if they
had to meet stringent complexity requirements.</p>
<p><b>Q.</b> Why doesn't <b>shared_ptr</b> provide (your pet feature here)?<br>
<b>A.</b> Because (your pet feature here) would mandate a reference counted (or a link-list, or ...) implementation. This is not the intent.
