Feature #4234: Hash#default_proc= Doesn't Accept nil Argument
https://bugs.ruby-lang.org/issues/4234#change-25730

Author: runpaint (Run Paint Run Run)

Priority: Normal
Assignee: marcandre (Marc-Andre Lafortune)
Category: core
Target version: 


=begin
 The initial value of a Hash's default Proc is the block passed to Hash.new or nil. Hash#default_proc= can set the default Proc to a given Proc, but can't reset it to nil. This is unsymmetrical. 
 
 The attached patch lets #default_proc= take a nil argument, and provides tests. This causes a RubySpec failure ("Hash#default_proc= raises an error if passed stuff not convertible to procs"), which I will fix if this patch is applied.
