[issue36358] bool type does not support True or False as command line argv

[Serhiy Storchaka]

Yes, this is expected. bool('False') is True.

You can write your own converter which returns True for 'True', False for 'False' and raise an exception otherwise.

But it is more common to add a pair of options without arguments --foo/--no-foo, or --with-foo/--without-foo, or --enable-foo/--disable-foo using the "store_const" action with True/False value.
