Summary: xrange() builtin accepts keyword arg silently
Initial Comment:
Calling ``xrange(10, 100, step=10)`` results in a
xrange(10, 100) iterator silently. In contrast,
``range(10, 100, step=10)`` raises an exception. See
test program below.
Two possible fixes:
1. fix xrange() so that it returns a xrange(10, 100,
10) iterator
2. make sure that xrange() raises an exception too.
#!/usr/bin/env python
def foo( min_, max_, step=1 ):
print min_, max_, step
print '===================='
foo(10, 100, 10)
foo(10, 100, step=10)
print '===================='
print xrange(10, 100, 10)
print xrange(10, 100, step=10)
print '===================='
print range(10, 100, 10)
print range(10, 100, step=10)
elbow:/usr/.../lib/python2.4$ /tmp/a.py
====================
10 100 10
10 100 10
====================
xrange(10, 100, 10)
xrange(10, 100)
====================
[10, 20, 30, 40, 50, 60, 70, 80, 90]
Traceback (most recent call last):

TypeError: range() takes no keyword arguments
