But Py2's print is not just a procedure. It's magical syntax. You
can't create your own procedures.
Why SHOULD they be special? Ultimately, a procedure is simply a
function that has no useful return value; and there are myriad times
when I've called a function or method for its side effects and ignored
the return value. So do I need to be able to "call a function as if it
were a procedure", or is there a stark difference between the two
types of callable?
Where, in any useful production code, is the difference between
functions and procedures actually helpful? Or where, in student code,
would it be useful to distinguish? I've been teaching Python to
students with a variety of backgrounds, and nobody has yet been
bothered by this. Not a single one.
