No, I was noting you also missed the 'AnyDBM_File' thing in your tie
statement, the CLASSNAME.  You can use variables for flags, I rarely do,
those were just placeholders.

That's fine (though, stylistically, I prefer 'or' instead of '||' when I am
saying "do X or Y", whereas I use '||' for "Z = X || Y", but if you have
parens around your tie() arguments, '||' works just fine.  But I am
babbling now, so ignore me :).
