[Python-ideas] Optional keepsep argument in str.split()

[Marco Buttu]

What do you think about an optional `keepsep` argument in str.split(), 
in order to keep the separator?
Something like the `keepends` of str.splitlines():

     >>> 'I am\ngoing\nto...'.splitlines(keepends=True)
     ['I am\n', 'going\n', 'to...']

For instance:

     >>> 'python3'.split('n')
     ['pytho', '3']
     >>> 'python3'.split('n', keepsep=True)
     ['python', '3']

Regards, Marco
