Not really. Or more precisely, your assumption where is_abstract is
known to work is too broad. The problem is, is_abstract fails with gcc
3.4 for non-trivial examples. I reported this in 

<URL:http://lists.boost.org/MailArchives/boost/msg10998.php>.

IIUC, this bug will be fixed in gcc 4.x, but not in the gcc 3.4
release series, cf. 
<URL:http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17232>.
