bug.pp

function test() {
  $a = notify { "hi it's me": }
  {asd => 42,}
}
$b = test()

# Error: Could not parse for environment production: Expression is not valid as a resource, resource-default, or resource-override (file: /tmp/function_bug.pp, line: 2, column: 8) on node managua.lan

Just as weird:

function test() {
  $b = 84

  {
    asd  => 42,
    text => $b,
  }
}

$b = test()
notify { "it's a bug! ${b}":}
# Error: Could not parse for environment production: Expression is not valid as a resource, resource-default, or resource-override (file: /tmp/function_bug.pp, line: 2, column: 8) on node managua.lan

Even worse!

With underscore:

function test() {
  $a = 84

  {
    asd  => 42,
    _text => $a,
  }
}
$b = test()

Without underscore:

function test() {

  {

    text => $a,
