could it be that the placeholder-magic is faked by DBD/DBD::MYSLQ and that it simply relies on quoting and interpolating the placeholders? That would of course be a Bad Thing.
Not necessarily. The DBD::MySQL driver is likely to have been written by someone competent, who understands how to do the correct quoting to make it injection proof; this is in contrast to typical user-level code, which has a good chance of getting it wrong. So even faked placeholders buy you security.
