> Here is another idea. In
[http://www.ginac.de/reference/mul_8cpp_source.html#l00442 the Ginac
source], we have
> {{{
> 00464 } else if (seq_size==1 && overall_coeff.is_equal(_ex1)) {
> 00465 // *(x;1) -> x
> 00466 return recombine_pair_to_ex(*(seq.begin()));
> }}}
This is currently in Pynac:
https://github.com/pynac/pynac/blob/master/ginac/mul.cpp#L741
> and that could be somehow changed. And the other issue is
[http://www.ginac.de/reference/inifcns__trans_8cpp_source.html#l00303
here]
> {{{
> 00319 if (z.is_equal(*_num0_p)) // sin(0) -> 0
> 00320 return _ex0;
> }}}
And this is currently
https://github.com/pynac/pynac/blob/master/ginac/inifcns_trans.cpp#L430
