In Python str.split method has an optional argument (named maxsplit), the
number of times to split:
http://docs.python.org/2/library/stdtypes.html#str.split


>>> "5  red blue".split()
['5', 'red', 'blue']
>>> "5  red blue".split(" ", 1)
['5', ' red blue']
>>> "5  red blue".split(None, 1)
['5', 'red blue']


>>> "red blue  10".rsplit()
['red', 'blue', '10']
>>> "red blue  10".rsplit(" ", 1)
['red blue ', '10']
>>> "red blue  10".rsplit(None, 1)
['red blue', '10']


It's handy when you have a not uniform string that you want to split partially:

>>> t = "20  Walter Bright"
>>> n, name = t.split(None, 1)
>>> n
'20'
>>> name
'Walter Bright'


I think such optional argument could be useful in Phobos split as well.
