Class parameter scope is not used when resolving qualified names

Looking at https://puppet.com/docs/puppet/5.0/release_notes.html there was a language deprecation that was missed.

In Puppet 4, the following code works as expected and prints 'does it work yes'

class foo ( 

  $var1 = 'does it work',

  $var2 = "${foo::var1} yes"

) { 

  notice($var2)

}

include 'foo'

In Puppet 5, the same code only prints ' yes'

Apparently, there was a change in the parser that means that local names can only be used when referencing earlier parameters.

The corrected code would be:

class foo ( 

  $var1 = 'does it work',

  $var2 = "${var1} yes"

) { 

  notice($var2)

}

include 'foo'
