Kwalitee and the prompt() method

pokki has asked for the wisdom of the Perl Monks concerning the following question:

Hello monks,

This page on Kwalitee mentions the optional indicator "no_stdin_for_prompting":

no_stdin_for_prompting
Shortcoming: This distribution is using direct call from STDIN instead of prompt())
Remedy: Use the prompt() method

This seems to suggest that there is One True prompt method to be used. Poking around on CPAN gives me IO::Prompt and Term::Prompt, both of which define a prompt(). Should I use one of these? Which is recommended? Can I implement my own prompt()? (Probably shouldn't.) If it's called something else, will kwalitee tests nag me for using <STDIN> in that method?

Am I just nitpicking? A huge majority of distributions are complying to this, according to CPANTS -- maybe because most don't use STDIN anyway, directly or indirectly?

(I have no actual use case to present. This is just me being curious.)

See `prompt` in ExtUtils::MakeMaker. Its advantage is that it can be modified by environment variables to not prompt, but to return the default -- which in turn makes fully automated installs much easier. Perl 6 - second systems done right	[reply] [d/l]

Ohhh. Yeah, I was definitely looking in the wrong direction for this. Thanks for the clarification!	[reply]

There is a prompt() method/function in ExtUtils::MakeMaker as well as in Module::Build and Module::Install (moritz explained what it is good for), so that the recommendation will work for whatever you use as an installer.	[reply]
