Anyone using $dbh->{Handlers} attribute ?

Don't be surprised if you haven't heard of the Handlers attribute,
it's not documented.  And don't bother finding out about it because
it's probably going away.

But I think I have mentioned it a couple of times and wanted to
check if anyone was using it for anything? And if so, what (so
I can try to make sure there's a better way to do the same thing.)
