Here's a real-world C example, took us several weeks to track down - all the
programmer did was add some debugging code:


  if ( is_student(person) )
        log("update student %s", person->name );

Everybody has their courses updated whether students or not - why???

On the hardcopy, the update_courses() call was the last line on the page,
which made it that much harder to spot.

In fact, you can cite examples on this argument in either direction; it is
more than a little condescending to preach that "in the real world, my way
is the right way."

As far as Python goes, I think bracelessness is one of its defining
features; if some day braces were to get included in Python a la C or Java,
then it will cease to be Python.
