Subject: [ruby-core:70888] [Ruby trunk - Feature #11547] [Open] remove	top-level constant lookup

Issue #11547 has been reported by Corin Langosch.

----------------------------------------
Feature #11547: remove top-level constant lookup
https://bugs.ruby-lang.org/issues/11547

* Author: Corin Langosch
* Status: Open
* Priority: Normal
* Assignee: 
----------------------------------------
If ruby cannot find a class in the specified scope it uses the top-level constant of the same name if it exists and emits a warning:

~~~
irb(main):006:0> class Auth; end
=> nil
irb(main):007:0> class Twitter; end
=> nil
irb(main):008:0> Twitter::Auth
(irb):8: warning: toplevel constant Auth referenced by Twitter::Auth
=> Auth
~~~

In some cases this is not playing nicely with rails autoloading as can be seen here: https://github.com/rails/rails/issues/6931. Many more issues like this exist.

Imo I don't see any reason why this fallback makes any sense. So I'd like to suggest to remove it completely or at least add an option to disable it.
