Nice! Too bad this tidbit isn't in Stroustrup (unspecial edition),
page 854, section C.13.1.

Unfortunately, this also has the drawback (under vc6sp4, anyways) of
causing the static to be multiply defined if the same template 
instantiation is made in more than one compilation unit. It seems
to be the equivalent of defining a non-template member in a header
and then including it in more than one compilation unit.

Thanks,

- Eric
