Bug #8507: Keyword splat does not convert arg to Hash
https://bugs.ruby-lang.org/issues/8507#change-47862

* Author: Stephen Celis
* Status: Feedback
* Priority: Normal
* Assignee: Yukihiro Matsumoto
* Category: syntax
* Target version: current: 2.2.0
* ruby -v: ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin12.3.0]
* Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN
----------------------------------------
A single splat is useful to convert an object to an array as it passes from one method to the next, so I expected the double-splat to do the same and convert the object to a hash.

~~~ruby
def splat *args
  p args
end
def double_splat **kwargs
  p args
end
splat(*nil)  # []
splat(**nil) # TypeError: no implicit conversion of nil into Hash
~~~

For the sake of consistency, wouldn't it make sense to wrap the double-splatted arg with `Hash()` the same way a single-splatted arg is wrapped with `Array()`?
