So, the specification at https://github.com/puppetlabs/puppet-specifications/blob/master/language/types_values_variables.md states: NamedVariable : /[a-z_]\w*/ | /(::)?[a-z]\w*(::[a-z]\w*)*/ That implies to me that fooBar would work, because the first character is part of [a-z_], and all successive characters have to be a word character (i.e. upper or lower case). I had a quick chat with Henrik Lindberg in IRC, turns out that the future parser in 3.7 should behave as in 4.0 -- so if fooBar works now, it will work in future. He specifically told me "CamelCase is ok as long as the camel starts with a c and not a C" and that "internall[y], all names of classes etc is turned into lower case anyway" So, Java fans, looks like camelCase lives on. snake_case seems to be the preferred option for puppet, but it's not strictly enforced. Hope that clears things up. As I understand it, the documentation at https://docs.puppetlabs.com/puppet/latest/reference/experiments_future.html will be updated.
