Bug #12029

Updated by nobu (Nobuyoshi Nakada) over 8 years ago

When count is called on an enumerable that yields multiple elements, not all elements are yielded to the block. 

 ~~~ruby ~~~ 
 def foo 
   yield 1, 2 
 end 

 to_enum(:foo).count { |e| e == [1, 2] } 
 # Returns: 0 
 # Expected: 1 
 ~~~ 

 It appears that only the first element is yielded: 

 ~~~ruby ~~~ 
 to_enum(:foo).count { |e| p e; e == [1, 2] } 
 # Prints 1 
 ~~~
