[New-bugs-announce] [issue24754] argparse add_argument with action="store_true", type=bool should not crash

[Douglas Bagnall]

New submission from Douglas Bagnall:

A line like this:

    parser.add_argument('--hello', action="store_true", type=bool)

causes a TypeError in 2.7 and 3.4:

   File "/usr/lib/python3.4/argparse.py", line 1344, in add_argument
     action = action_class(**kwargs)

     TypeError: __init__() got an unexpected keyword argument 'type'

It shouldn't really.
