What other folks do

class A:
   def do_run( self ):
       """Must be overridden."""

       You were warned.
       """
       print "PRE"
       return_value = self.do_run(*args, **kw)
       print "POST"

If you want to worry about someone "breaking" this, stop now. Don't waste time worrying.

It's Python. We're all adults here. All the malicious sociopaths will break all you code by copying it, changing it, and then breaking it. No matter what you do, they'll just copy your code and modify it to break the clever bits.

Everyone else will read your comment and stick by your rules. If they want to use your module/package/framework, they will cooperate.
