Since it's been a few years and this was never added, I decided to take a shot at doing it in the repl.rc. Use this if you want to patch around the problem: # fix Term::ReadLine::Gnu to allow $! if ($_REPL->term->ReadLine eq 'Term::ReadLine::Gnu') { $_REPL->term->Attribs->{history_expansion_char} = ''; $_REPL->term->Attribs->{history_subst_char} = ''; }
