Making file writable

[John Soo]

Hey Tomás,  

  
Check your parens:
  

  
(for-each (make-file-writable (find-files "\\.yml$")))
  

  
Should be   
  

  
(for-each   make-file-writable (find-files "\\.yml$"))
  

  
That’s because for-each is a higher order function which takes a procedure and 
a list.
  

  
Good luck!
  

  
- John
