Feature #9451
Updated by nobu (Nobuyoshi Nakada) over 4 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.
