Issue #2053 has been updated by Andrew  Parker.

I think that killing relative names would be great in terms of "principle of 
least surprise", but I'm uncertain what the deprecation and replacement would 
look like. Simply warning that something would result in a relative lookup 
seems unfriendly because they would have to use the ugly `::` prefix which 
during the dynamic scope deprecation period caused a lot of unhappiness.

So what would the deprecation and new world look like?

Bug #2053: Relative namespacing of class/define names results in big surprises
https://projects.puppetlabs.com/issues/2053#change-68771

Author: Lawrence Ludwig
Status: Needs Decision
Priority: Normal
Assignee: eric sorenson
Category: modules
Target version: 
Affected Puppet version: 0.24.7
Keywords: telly deprecation modules classes namespaces names
Branch: 


Due to Puppet's relative namespacing of class names, `include bar` does not 
mean "declare class `bar`." It actually means "try to declare class `<current 
namespace>::bar`, class `<parent of current namespace>::bar`, and so on, 
declaring class `bar` only as a last result."

    class bar {
      notice("From class bar")
    }
    class foo::bar {
      notice("From class foo::bar")
    }
    class foo {
      include bar
    }
    include foo

This is maximally surprising, especially considering the prevalence of things 
like:

    class apache::nagios {
      include nagios # joke's on you, because this just includes apache::nagios 
again
    }
