Subject: [ruby-core:84931] [Ruby trunk Bug#14374] `for` does not splat	elements

Issue #14374 has been reported by nobu (Nobuyoshi Nakada).

Bug #14374: `for` does not splat elements
https://bugs.ruby-lang.org/issues/14374

* Author: nobu (Nobuyoshi Nakada)
* Status: Open
* Priority: Normal
* Assignee: ko1 (Koichi Sasada)
* Target version: 
* ruby -v: 2.6
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
In general, it is said that `for` statement and `each` method call are  similar, except for the scope of loop variables.
I found another difference, since 1.9.

```ruby
a = [Struct.new(:to_ary).new([1, 2])]
a.each {|i, j| p [i, j]} #=> [1, 2]
for i, j in a; p [i, j]; end #=> [#<struct to_ary=[1, 2]>, nil]���
```

In 1.8, the latter result equals the former.
Is this intentional?
