But you impact legibility:

  mo = findSomething.search(someString)
  while mo:
	....
	....
	mo = findSomething.search(someString)


is much more understandable than:


  while mo = findSomething.search(someString):
	....
	....
	mo = findSomething.search(someString)


because *that* can be confused with *this*


  while flag == object.method(something):
	....
	....


and confusion ensues.


no?

I'd sincerely prefere the more readable alternative.
