I assume you changed the second string to "Uh.". If so, then that is
what is supposed to happen. $term->readline() prompts with the first
string with a default of the second. When you hit enter, the input is
stored in $answer. All my loop does with the answer is tell you what
you said.

Package refers to the multiple readline backends which are implemented
as modules (Term::Readline::GNU, Term::Readline::Perl, etc.). Some of
these backends have more features than others, but you always have
access to a base level of functionality in Term::Readline::Perl.
Stubs are short functions that don't do anything. They are needed in
case the backend does not provide a feature. The stub will be called
instead and do nothing. This will prevent the program from blowing
up, allowing it to run with reduced functionality. For instance, a
backend might not provide a history of previous entries. In that
case, addhistory won't do anything, but calling it won't cause a
runtime error.
A method is a subroutine called on an object:
$obj->method();
