What Jython users will appreciate is that the above suggestion -- although
it might be handy for Pythonic structures and, possibly, might be "more
logical and intuitive" than other suggestions -- doesn't necessarily help
with the world of structures one encounters outside the arena of 100%
Python.  Java/Swing tables, for example, cannot be passed to the Python len
() function (they are two-dimensional, for starters, and are not defined as
a sequence of sequences).  So such an extension to the range() function
won't make it any easier to deal with (certain) Java structures in Jython.
PEP 276, for example, suggests a simple way to deal with index-based
structures that have been designed outside the sphere of Python practices
while also making it easier at times to deal with Pythonic designs.
