[New-bugs-announce] [issue25628] Make namedtuple "verbose" and "renanme" parameters into keyword only arguments

[Raymond Hettinger]

New submission from Raymond Hettinger:

This is a usability and readability improvement made possible by Python 3's keyword only arguments.

Usability is improved by getting a much less confusing response from the following mistake:

    namedtuple('Point', 'x', 'y')
                              ^--- invisibly goes to the "verbose" argument 

The "verbose" argument is normally used interactively (much like help() and dis()) or is used with a keyword argument, so it is unlikely that existing scripts will be much affected.  For the rare cases, the remediation is simple and improves code clarity (replacing "True" with "verbose=True").
