   It is in fact quite a common thing. Look at the examples of use   
   of the open() function in the standard Python library docs   
   , for instance.   
      
   There is another call to open() on that page, in an example for another   
   function, and that uses a with-statement too.

   This is the old “do as I say, not as I do” school of writing example code.   
   You tell people to understand what the code does and use it as a model,   
   not just blindly copy-and-paste, and ... guess what they do?

   In other words, precisely the ones who are in a hurry to get something   
   done, finish an assignment or whatever, and therefore ... blindly copy-   
   and-paste.

   One would hope so, but given some discussions that have been happening   
   recently, I’m not so sure ...
