Issue #22219 has been updated by Henrik Lindberg.
Subject changed from Class Scope Gotcha to Issue warning when class includes
itself
Status changed from Unreviewed to Accepted
Since it is meaningless for a class to include itself and an indication that
something is not right, it should at least lead to a warning. (Or even an
error).
Why it even tries to resolve "zamboni" against itself ("role::zamboni") is a
mystery since the name space it is in is really "role::zamboni" and it would
have made sense to find "role::zamboni::zamboni" (if that existed), but not
itself).

Bug #22219: Issue warning when class includes itself
https://projects.puppetlabs.com/issues/22219#change-96508
* Author: Dirk Elmendorf

----------------------------------------
Summary: When you include a class inside a class and they have similar names
then the new class does not get included.
Steps to Reproduce:
<pre>
class zamboni {
notice("Class zamboni included")
}
class role::zamboni {
notice("Class role::zamboni included")
include zamboni
}
class role::server {
notice("Class role::server included")
include role::zamboni
}
</pre>
Expected Results:
Should include role::server,role::zamboni,:zamboni
Actual Results:
role::server and role::zamboni are included. role::zamboni believes that the
include zamboni is referring to itself so it does not include the class
zamboni. It still seems like there should be a warning since it doesn't really
make sense that I would include a class in itself.
Workaround:
If I include ::zamboni in role::zamboni it doesn't get confused.
Notes: I used zamboni to make it clear what is going on. I discovered the issue
when I was working with the role::database::mysql & mysql
The mysql module is from the Puppet forge.
