pp.c:166

    else if (gimme == G_SCALAR) {
    SV* sv = sv_newmortal();
    if (HvFILL((HV*)TARG))
        Perl_sv_setpvf(aTHX_ sv, "%ld/%ld",
              (long)HvFILL((HV*)TARG), (long)HvMAX((HV*)TARG) + 1);
    else
        sv_setiv(sv, 0);
    SETs(sv);

dann perldoc perlapi: /HvFILL

"number of hash buckets that happen to be in use" vs.
"total number of hash buckets".

warum sie es so machen weiss ich nicht, es soll sich
aber ändern: http://dev.perl.org/rfc/196.html
