----------------------------------------
Bug #20094: Inline while loop behavior changed unexpectedly in 3.3.0
https://bugs.ruby-lang.org/issues/20094#change-105932

* Author: sisyphus_cg (Sisyphus CG)
* Status: Closed
* Priority: Normal
* ruby -v: 3.3.0
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
The behavior of the inline while loop has changed in 3.3.0. This unexpectedly broke my code and I couldn't find anything in the changelog about it so reporting it as a bug.

In ruby <= 3.2:

``` ruby
(p 1) while false      # nothing
(p 1; p 2) while false # nothing
```

In ruby 3.3:

``` ruby
(p 1) while false      # 1
(p 1; p 2) while false # 1 2
```

Essentially, if the left hand side looks like a statement, now it is treated as a do-while loop. In ruby 3.2 and less this only happened with explicit use of `begin` and `end`.
