first argument specifies the message to display to the user (for
example, C<"Where do you keep your money?">).  The second argument,
which is optional, specifies a default answer (for example,
C<"wallet">).  The user will be asked the question once.

If C<prompt()> detects that it is not running interactively and there
is nothing on STDIN or if the PERL_MM_USE_DEFAULT environment variable
is set to true, the $default will be used without prompting.

To prevent automated processes from blocking, the user must either set
PERL_MM_USE_DEFAULT or attach something to STDIN (this can be a
pipe/file containing a scripted set of answers or /dev/null.)

If no $default is provided an empty string will be used instead.  In
non-interactive mode, the absence of $default is an error (though
explicitly passing C<undef()> as the default is valid as of 0.27.)

This method may be called as a class or object method.
