 $ ./ruby -e 'Proc.new{|k: 0|}.()'
 -e:1:in `block in <main>': undefined method `key?' for

 $ ./ruby -e '

   yield
 end
 m{|k: 0|}
 '
 -e:5:in `block in <main>': undefined method `key?' for nil:NilClass 
(NoMethodError)

 $ ./ruby -e 'lambda{|k: 0|}.()'

I think Proc/block should take keyword arguments as well as lambda.
I've attached a patch.
