Feature #9451

Updated by nobu (Nobuyoshi Nakada) over 5 years ago

Not sure if this is a bug or feature request:

~~~ruby


require 'minitest/autorun'

require 'set'



module ClassToProc

refine Class do

def to_proc

lambda{ |*args| self.new(*args) }

end

end

end



using ClassToProc



describe 'Class#to_proc' do

it 'works when called directly' do

Set.to_proc[[1,2]].must_equal Set[1,2]

end



it 'fails when called via ampersand' do

[[1,2]].map(&Set).must_equal [Set[1,2]]

end

end
~~~


The second example errors with *NoMethodError: super: no superclass method `to_proc' for Set:Class*

Would be great to have it, though.
