Bug #7630: Proc/block doesn't take keyword arguments

• Status: Closed
• Assignee: ktsj (Kazuki Tsujimoto)
• Target version: 2.0.0
• ruby -v: ruby 2.0.0dev (2012-12-28 trunk 38642) [x86_64-linux]

=begin
$ ./ruby -e 'Proc.new{|k: 0|}.()'
-e:1:in block in <main>': undefined method key?' for 70368666077121:Fixnum (NoMethodError)

$ ./ruby -e '
def m
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.

It seems accessing out of the stack, so I think this bug is critical.
Please fix it with a test.
