[Dbix-class] can i add custom error info for throw_exception in dbix::class 0.07006?

[老邪]

hi, all
    i have a question about dbix::class 0.07006 ( i know it's old, but my
codes are base on it...). i want to add host IP of mysql db into the error
info of dbix's exception.
so that it's helpful for us to debug our codes.
   i just read the doc of newest version of dbix::class (0.08121), seems it
provide a way to make a custom throw_exception myself. then i read doc of
0.07006, doesn't
see such method as 0.08121.
   so, i wanna ask, is there any anything i can do to add host IP into error
info of dbix's exception of version 0.07006
   any tips are appreciated. thank you !
