Subject: [ruby-core:94970] [Ruby master Bug#12984] `rescue *[]` should be equivalent to `rescue` as `method_call(*[])` is equivalent to `method_call`

Issue #12984 has been updated by matz (Yukihiro Matsumoto).

Status changed from Assigned to Closed

This `*[]` is not just exception list omitted, but explicitly specifies zero exceptions to catch.
Thus the current behavior is intended.

Bug #12984: `rescue *[]` should be equivalent to `rescue` as `method_call(*[])` is equivalent to `method_call`
https://bugs.ruby-lang.org/issues/12984#change-81587

* Author: bughit (bug hit)
* Status: Closed
* Priority: Normal
* Assignee: matz (Yukihiro Matsumoto)
* Target version: 
* 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 supposed 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
```
