I don't think this is doing what you think it is doing ;-)

>> def local(&block);yield block;end
=> nil
>> local{|x| p x}
#<Proc:0x401f8ee0@(irb):2>
=> nil

for the matter,

>> def local; yield 1;end
(irb):3: warning: method redefined; discarding old local
=> nil
>> local{|x| p x}
1
=> nil
>> local{|a,b,c| }
=> nil
