Umm, not officially currently but there's a good chance that keys
%{$sth->{ParamValues}} would work on many drivers that support it.
I'll add a note to that effect in the docs so that'll become the
standard way.
A slight downside is that it won't be possible to tell the difference
between a placeholder that's not been bound and one that has but
was bound to undef. But I don't think that'll be a big issue.
Anyone disagree?
Tim.
