[ruby-core:55492] [ruby-trunk - Bug #8507] Keyword splat does not convert arg to Hash

From: "kainosnoema (Evan Owen)" <kainosnoema@...>
Date: 2013-06-14 21:38:51 UTC
List: ruby-core #55492
Issue #8507 has been updated by kainosnoema (Evan Owen).


I'm glad this is getting addressed. Handling nil values is one of the most tiring and error-prone aspects of coding in Ruby. Much has been said about the mistake of introducing NULL references in languages (http://www.infoq.com/presentations/Null-References-The-Billion-Dollar-Mistake-Tony-Hoare, among others), and there are considerable efforts being made in many places to remove much of the pain that they cause.

I've also personally run into the situation shown in stephencelis's example above, and was quite surprised and disappointed by it. I'm 100% in support of any effort to gracefully handle nil values when coercing. The consistency added by stephencelis's patch is a big win, IMO.
----------------------------------------
Bug #8507: Keyword splat does not convert arg to Hash
https://bugs.ruby-lang.org/issues/8507#change-39936

Author: stephencelis (Stephen Celis)
Status: Feedback
Priority: Normal
Assignee: matz (Yukihiro Matsumoto)
Category: syntax
Target version: current: 2.1.0
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


=begin
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.

  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()}))?
=end
