The other important part is that prompt() knows about buffering, and so
if PERL_MM_USE_DEFAULT is *not* set, then there's a much better chance
that a real user who is, eg, piping CPAN.pm's output through another
programme (such as tee) will actually see what questions you're asking
him.
If you just print to STDOUT and read directly from STDIN, users will
sometimes not see the questions until after they've answered them. Or
more likely, they'll think your Makefile.PL crashed.

You may now start misinterpreting what I just
