Backport #9299
Required keyowrd arguments and arity
Description
While fixing #8072, I noticed another bug: a required keyword argument should add 1 to the arity:
proc{|required:|}.arity # => 0, should be 1

Like #8072, this is not a simple backport.
Please get confirmation by matz

Please excuse my ignorance, I'm not sure what a simple backport is.
Dear Matz, hopefully you will know.
I always put my bug fixes as backport requests, but I welcome guidelines.

Updated by I consider this as a bug. So it should be back-ported to 2.1, I think.

yeah, I know you understand backport policy.
What I wanted to say is "I don't understand Proc#arity's keyword argument spec and can't judge whether spec change or bug fix".
(I accidentally backported #8072 related another backport, but the main issue is the spec of arity for keyword arguments)
Therefore could you describe the spec to Proc#arity's rdoc?
I want to backport it to Ruby 2.1.2.
Anyway I had written HowToRequestBackport.
The use of Backport custom field will help you.

Naruse-san: You're right, the rdoc of Proc#arity was quite out of date. I've committed r45236-r45238 (04042ec6eb4..47d6a7ee1c8) to address this.
Matz: would you have time to review the rdoc of Proc#arity, especially the part about the different treatment of lambdas vs procs?
Thanks
