Actually, DBI is where I was thinking of bringing it in, combined with a custom $SIG{__DIE__}, eg:

local $SIG{__die__} = sub {
    die ("DBI Error: $DBI::errstr") if $DBI::errstr;
    die $!;
};

But make sure you explicitly refer to the error (ie, don't use OO method unless method will definitely be in scope in the sub).

Could be very useful...
