[ruby-core:81579] [Ruby trunk Bug#13623] meta-programming, adding sub-module fails with syntax error

Ok, you make it very clear. Indeed, in working_meta 'Bar' is not a constant but a name when statement 'module' is evaluated. Statement 'module' requires a name that does not exist in the scope yet. That name can be preceded by an expression that results in a scope. Default is the current scope. Name and scope expression are separated by double colon.

Bug #13623: meta-programming, adding sub-module fails with syntax error
https://bugs.ruby-lang.org/issues/13623#change-65282

* Author: caschip (Aad Schippers)
* Status: Rejected
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
The goal is to add a sub-module to a higher level module. The higher level module is derived from its name in a string. This works in one case and gives an unexpected syntax error in another case.

```
failing_meta:4: syntax error, unexpected '\n', expecting &. or :: or '[' or '.'
failing_meta:8: syntax error, unexpected keyword_end, expecting end-of-input
```
