Subject: [ruby-core:82732] [Ruby trunk Bug#13844] Toplevel returns should	fire ensures

Issue #13844 has been updated by nagachika (Tomoyuki Chikanaga).

Backport changed from 2.2: DONTNEED, 2.3: DONTNEED, 2.4: REQUIRED to 2.2: DONTNEED, 2.3: DONTNEED, 2.4: DONE

ruby_2_4 r59812 merged revision(s) 59708.

----------------------------------------
Bug #13844: Toplevel returns should fire ensures
https://bugs.ruby-lang.org/issues/13844#change-66574

* Author: headius (Charles Nutter)
* Status: Closed
* Priority: Normal

* Target version: 
* ruby -v: 2.4.1
* Backport: 2.2: DONTNEED, 2.3: DONTNEED, 2.4: DONE
----------------------------------------
In the following contexts, a return always fires the ensure that wraps it:

```
[] ~/projects/ruby $ ruby -e 'def foo; return; ensure; p :x; end; foo'
:x

[] ~/projects/ruby $ ruby -e 'def foo; 1.times { begin; return; ensure; p :x; end }; end; foo'
:x
```

However the new 2.4 support for toplevel returns does *not* fire ensures:

```
$ ruby -e 'begin; return; ensure; p :x; end'
<no output>
```

I believe this is inconsistent with how returns work everywhere else (both valid and invalid returns always fire ensure) and it should be changed to match.
