IMO: The possibility to add new keyword arguments with default values
is one of the major strengths Python has compared to other programming
Especially in the scenario, where an existing mature API has to be
enhanced later with added features:
In such a situation I always prefer APIs with fewer functions
(may be with large lists of optional arguments) compared to APIs
containing a bunch of functions or methods called 'popen2()',
'gethostbyname2()' and so on.
