Ruby

Hi

Are the following differences intentional?

$ ruby -v ruby 2.7.0dev (2019-03-18 trunk 67291) [x86_64-darwin18] 

$ cat ptn1.rb a = -> { p @1 } a.call(1) $ ruby ptn1.rb Traceback (most recent call last): 1: from ptn1.rb:2:in `<main>' ptn1.rb:1:in `block in <main>': wrong number of arguments (given 1, expected 0) (ArgumentError) 

$ cat ptn2.rb a = lambda { p @1 } a.call(1) $ ruby ptn2.rb 1 

thanks
