Detecting a tied variable in TIEHASH

I have a bug report for DB_File where a hash tied to DB_FILE gets re-tied,
and things don't work very well.

 

So something like this is going on

 

    tie %h, "DB_File",.

    .

    tie %h, "DB_File",.

 

Ideally I'd like to trap this in TIEHASH, but I don't think there is a way
to detect it. "tied" isn't going to help because the variable to be tied
isn't available.

 

Is this a feature gap or have I forgotten something?
