For reference the current docs are @ https://docs.puppetlabs.com/puppet/latest/reference/lang_reserved.html#variables And according to the rules in that doc, this still works in 3.7.x at least: puppet apply -e '$fooBar="1" notice($fooBar)' --parser=future This though fails: puppet apply -e '$FooBar="1" notice($FooBar)' --parser=future Error: Illegal variable name, The given name 'FooBar' does not conform to the naming rule /^((::)?[a-z]w*)*((::)?[a-z_]w*)$/ at line 1:1 Which is weird because 'fooBar' also doesnt match this rule so why did it work? -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
