Hi Xho,
Sorry - didn't mean to impugn the quality of the docs. All I was
looking for is some sort of article from a trade rag, for instance,
that discussed the utility of those code blocks. You know, maybe some
sort of article where a really good Perl programmer describes how he
(or she :) ) uses those code blocks in an effective manner.
That's all.
