String comparison using in doesn't work with unless

Question

I want to check, if a given string is inside an array and if it isn't, I want to execute the code inside. However the in function seems to work with if only, when I use unless I get the following error.

Could not parse for environment production: Syntax error at 'in'; expected '}'

Code looks like this:

$string = 'abc'
$array = ['abc', 'def', 'ghi']

unless $string in $array {
  do xxx
}

what is going on? I use Puppet 2.7

Your code works with Puppet 3.7.

2.7 seems to have no unless at all.

Try an if ! x construct, or work around the issue using

if $foo in $bar {
    # noop
} else {
    # your code here
}
