Issue #1705 has been reported by rgsteele.

----------------------------------------
Bug #1705: AST::ASTArray needs to check for empty elements as well as nil 
elements when flattening
http://projects.reductivelabs.com/issues/show/1705

Author: rgsteele
Status: Unreviewed
Priority: Normal
Assigned to: 
Category: 
Target version: 
Complexity: Unknown
Affected version: 0.24.6
Keywords: 


This manifest:

   #!/usr/bin/env puppet

   $groups = ["foo", "bar", ""]
   $groups2 = ["baz", "quux"]

   $user_groups = [$groups, $groups2]

   notify { $user_groups: }

Returns this output:

   notice: quux
   notice: foo
   notice: baz
   notice: bar
   notice: 

Ideally, it should not return that empty element.  We can just add this before 
returning rets.reject on line 36 to fix it:

   36 rets.delete('')
   37 return rets.reject { |o| o.nil? }
