Subject: [ruby-core:78394] [Ruby trunk Bug#12984] `rescue *[]` should be equivalent to `rescue` as `method_call(*[])` is equivalent to `method_call`

Issue #12984 has been reported by bug hit.

----------------------------------------
Bug #12984: `rescue *[]` should be equivalent to `rescue` as `method_call(*[])` is equivalent to `method_call`
https://bugs.ruby-lang.org/issues/12984

* Author: bug hit
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.3.3p222 (2016-11-21 revision 56859) [x86_64-linux]
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
splatting an empty array to a construct that takes a list is suppose to be equivalent to specifying no list

```ruby
def foo
end

foo *[] #works

```

so `rescue *[]` should be equivalent to `rescue`

```ruby
begin
  raise 'error' #Uncaught exception
rescue *[]
  puts 'caught'
end
```
