Subject: Re: Confusion with block local variable declaration with block variable declaration within the pipe

its when each yields more than one object, then you can see a difference

{1=>"a",2=>"b",3=>"c"}.each{|x;y| p y}
nil
nil
nil

{1=>"a",2=>"b",3=>"c"}.each{|x,y| p y}
"a"
"b"
"c"


|x;y=0| is still an syntax error
