I'm suspect it is one of the "subtle and strange" behavoir. I suppose I should have just posted a link to the code in git hub. I guess I was expecting that this would be something that was going to jump out as something obvious. My apologies for not doing so. Here is the link:
https://github.com/therevmj/puppet-module-software/blob/master/manifests/init.pp I'm absolutely doing some "not so normal" things in this module to obtain the desired effect. While I liked that idea of loading this data by including a class, it probably makes more sense to extract all of the data in my [package_name].pp files into csv files or yaml and slurp that data in using 'extlookup'. Initially there was more logic in [package_name].pp files, but now that they are basically just case statements setting variables, they don't really need to be classes anymore. Using 'inline_template' to effectively let me do an 'eval( $software::$name::ensure )' wasn't my first inclination, but at the time it was what made the most sense. Thanks for taking the time to respond to my not-so-complete inquiry. It is much appreciated.
