Hi!  
I wanted to write this :

```
       infile = File.new("foo")
       infile.each do ....

  but typed in
      infile.read do ...
             ----
  and it ran with no results - and no error messages . After a 

```

few minutes of puzzlement  
I found it. What does ruby do with the block if the method does  
not  
take one ? . Why doesn’t ruby check this kind of errors ?

It does nothing with the block. I imagine it doesn’t check if a  
method takes a block because you’d have to inspect the source of the  
method everytime to check if it took one or not, since methods can  
change.
