Wrong, as you can see from the code I posted, not only the sub is affected, but the intended side-effect (of altering the call-by-reference argument) is missing without warning.

How is eval supposed to help here?

So in your opinion manipulating $_ is a bad design!?!
Could you please post some code-examples to illustrate your point of view?
