I'm not sure exactly how it all works; probably some combination
of and internal support from perl itself.  I think
all the fallback option actually does is set

    ${"APR::Error::()"} = 1

IMO the costs are comparable to everything else related to
using overload, so I don't expect it to be too costly.
I could be wrong though, so benchmark that if it's a concern.

I think so.  If not, I'd say that's a bug in itself.
