=head1 NAME

FP::Repl::Dependencies - hack to load Repl dependencies

=head1 SYNOPSIS

    use Chj::TEST use => 'FP::Repl::Dependencies';

=head1 DESCRIPTION

Term::ReadLine::Gnu does not allow to check for its presence
directly. When require'ing Term::ReadLine::Gnu, it gives an error
saying "It is invalid to load Term::ReadLine::Gnu directly.". That
makes it appear as unloadable when in fact it is present. And
depending on just Term::ReadLine is not enough, the repl will then
fail at runtime. Stupid.

So, this.

# now also depend on PadWalker etc.
