-  newfunction(:getvar, type: :rvalue, doc: <<-'DOC') do |args|
-    @summary
-      Lookup a variable in a given namespace.
-
-    @return
-      undef - if variable does not exist
-
-    @example Example usage
-      $foo = getvar('site::data::foo') # Equivalent to $foo = $site::data::foo
-
-    @example Where namespace is stored in a string
-      $datalocation = 'site::data'
-      $bar = getvar("${datalocation}::bar") # Equivalent to $bar = $site::data::bar
-
-    > **Note:** from Puppet 6.0.0, the compatible function with the same name in Puppet core
-    will be used instead of this function. The new function also has support for
-    digging into a structured value. See the built-in
-    [`getvar`](https://puppet.com/docs/puppet/latest/function.html#getvar) function
