I understand, but this means starting already to put (tiny)
inconsistencies into Python 3.0...

Unrelated: Ruby and Lisp use ? and ! at the end of the function/method
names to denote a predicate or a function that mutates in place (With
them the list.sort() may be called list.sort!() ). Using Python I
usually put an Q at the end of the name for this purpose. Can Py 3.0
support names ending with "?" too?
