I wasn't advocating the use of any of those recommendations. This was merely a response to the OP's request: "... wondering what the Perl Best Practices are ...". These are just those I thought applicable to the situation at hand; there may be others.

For what it's worth, I don't use Line Lengths but I do use Indentation and Tabs; I don't recall ever using Multiline Strings (but it seems sensible enough); I do use heredocs and theredocs; I don't use perltidy.
