Re: Overloaded make() with pybind11

Hi Daniel,
engineer's finest remark:

"That is an *interesting* problem"

The problem here is that the arguments don't really allow for deduction with "make" you
meant, so:

I'd quickly work around that using a lambda function; try something like

.def(py::init(
[](int dual_basis, int interleave) {
return decode_rs::make(dual_basis, int interleave);
}),
py::arg("dual_basis"),
py::arg("interleave"),
D(decode_rs,make)
);
