Overloaded make() with pybind11

[Daniel Estévez]

Hi,

I'm porting gr-satellites to GNU Radio 3.9. I have some blocks that have 
an overloaded make() method, for example:

https://github.com/daniestevez/gr-satellites/blob/master/include/satellites/decode_rs.h

Maybe this wasn't a very wise design decision on my side.

Now I'm wondering if it's possible to use this with pybind11, and if so 
how to do it.

gr_modtool bind (with pygccxml installed) is generating this:

https://gist.github.com/daniestevez/a3d0aaf7e6b2a68933ebb30e9043e7ac

which gives build problems like

/home/daniel/gr-satellites/python/bindings/decode_rs_python.cc: In 
function 'void bind_decode_rs(pybind11::module&)':
/home/daniel/gr-satellites/python/bindings/decode_rs_python.cc:39:39: 
error: no matching function for call to 'init(<unresolved overloaded 
function type>)'
   39 |         .def(py::init(&decode_rs::make),
      |                                       ^


Best,

Daniel.
