[ruby-core:70302] [Ruby trunk - Bug #10856] Splat with empty keyword args gives unexpected results

Issue #10856 has been updated by Marc-Andre Lafortune.


I feel this has to be fixed.

foo(**{}) should === foo(**Hash.new) in all cases, and I feel it should not raise an error.

Bug #10856: Splat with empty keyword args gives unexpected results
https://bugs.ruby-lang.org/issues/10856#change-53722

* Author: Sean Griffin
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin13]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
When keyword args are passed to a method with splat, and there are no keyword args, an empty hash is sent. I would expect no argument to be given, same as splat with an empty array. For example:

    def foo
    end

    foo(**{})

This causes an argument error, as an empty hash is passed. I would expect the same behavior as

    def foo
    end

    foo(*[])
