Default parameter value that is using other parameters is giving warning in Geppetto

[aadamovich]

The following simple define gives an error in Geppetto. Even though it works in Puppet.

define test(
  $user = $title,
  $group = $user
) {
  exec { "$user":
    command => "echo $group",
    path => "/usr/bin:/bin"
  }
}

This also occurs with interpolated variables, e.g.:

define test (
  $foo = $title,
  $bar = "/${foo}/bar",
) {
  ...
}
