I added a page to eZpedia which makes it easier for people familiar with PHP to switch to the template language: http://ezpedia.org/wiki/en/ez/template_language_for_php_developers
I'm not sure this helps you /dev/null. If you are familiar with other template/scripting/programming languages, feel free to add your own page on eZpedia to compare them with the eZ template language.
That is a very fine page! <i>I know I have pine'd for such a page of documentation on several occasions in the past. Thank you</i>
Perhaps entries could be added for asp.net, cfml, perl, sql, ruby, python by others if needed, which would be the first language after php to add an entry for??
