Puppet users - Dec 2013 - Geppetto complains about uninitialized variables in reduce function

Hello,

I''m using the following expression to format a list:

        $valid_environments = [''env1'',
''env2'', ''env3'']
        $env_message = $valid_environments.reduce |$message, $env| { 
"${message}, ${env}" }

It works at run-time (Puppet 3.2.4 standalone with "--parser=future").

However in Eclipse (v4.3.1), Geppetto (v4.0) shows these errors:

        Reference to not yet initialized variable: env''
        Reference to not yet initialized variable: message''

The workspace Puppet target version is set to "future".

Is there another syntax I could use to make Geppetto happy or is this a bug?

Thanks,
Igor.

That looks like a bug. Please report it here:

https://tickets.puppetlabs.com/browse/GEP

The errors are for the case when there are parameters to a class or 
define and the default value expression references one of the other 
variables - i.e. something like this

define foo($a = $b, $b = 3) { }

So, something is amiss with the validation for a lambda. I assume you 
have turned on the "future" under Puppet Target.
