One thing C::Singleton misses is a clear_instance method though, which is pretty much necessary for mod_perl work (I'm surprised Andy hasn't fixed this, since he does a lot of mod_perl stuff)... However copying the code is pretty trivial and adding that method is about another 3 lines. -- <Matt/> Fastnet Software Ltd.
