I think this could be fixed by modifying the termination of the asinh() implementation to return only the real component if ref($z) was untrue.
That is, instead of terminating the asinh() sub with simply:
return &log($t);
terminate with something like (untested):
my $ret = &log($t);
return (@{$ret->cartesian})[0] unless ref($z);
return $ret;
