新人问题~~~大家帮帮看看，谢谢

class SimpleProc   
   def to_proc   
       proc {"Simple Proc"}   
   end         
end   
     
def method   
    yield   
end   
  
obj = SimpleProc.new  
puts method(&obj)  

请问为什么结果是Simple Proc ??



谢谢·~~~~

class SimpleProc

def to_proc

proc {"Simple Proc"}

end

end

def method

yield

end

obj = SimpleProc.new

puts method(&obj)

yield 调用 proc
将obj to_proc 不就是 Simple Proc 吗

看看下面的例子就明白了
def method

yield

end

puts method {"hello"} ＃ hello
