ikegami: 
- local *_ does work if you put it in the do block like jdporter said
- ... want to protect the parent's %_

* Did you test this with the sub{}-example I provided in
   order to show context dependency?
* where would preservation of %_ (jdporter mentioned $_)
   usually be of some importance?

Regards & thanks
