Re^2: Hard time to make use of PPI

Thanks for your clarification. However, it's not "the docs" and "me", its only "the docs". What I presented was code from "the docs". So either they are fine, or they try to force to do everything else.

Considering the fact that your given code differs from that in "the docs" and works, "me"'d be careful to give "the docs" a general absolution. ;-)

Anyway, our unused subroutines identifier started just breathing.
