Subject: [ruby-core:55828] [ruby-trunk - Bug #8507] Keyword splat does not convert arg to Hash


Issue #8507 has been updated by stephencelis (Stephen Celis).


Tried my best to thoughtfully address questions before (http://bugs.ruby-lang.org/issues/8507#note-6). Does anyone have any additional thoughts on the matter?

Bug #8507: Keyword splat does not convert arg to Hash
https://bugs.ruby-lang.org/issues/8507#change-40333

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()}))?
