OUTPUT
T_AVREF
$arg = $var ? Perl_newRV(aTHX_ Perl_sv_2mortal(aTHX_ (SV *)
$var)) : &PL_sv_undef;
T_HVREF
$arg = $var ? Perl_newRV(aTHX_ Perl_sv_2mortal(aTHX_ (SV *)
$var)) : &PL_sv_undef;
The default typemap is just '$arg = newRV((SV*)$var);'. So the
differences are an sv_2mortal and the same sort of NULL -> undef
mapping that you were talking about.
