Bug #4234: Hash#default_proc=3D Doesn't Accept nil Argument
http://redmine.ruby-lang.org/issues/show/4234

Author: Run Paint Run Run
Status: Open, Priority: Low
Category: core
ruby -v: ruby 1.9.3dev (2011-01-05 trunk 30456) [x86_64-linux] =


The initial value of a Hash's default Proc is the block passed to Hash.ne=
w or nil. Hash#default_proc=3D 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=3D take a nil argument, and provide=
s tests. This causes a RubySpec failure ("Hash#default_proc=3D raises an =
error if passed stuff not convertible to procs"), which I will fix if thi=
s patch is applied.
