py::enum_ enum type enforcement in functions across python and c++

[db7894]

Hi there, I have a C++ enum class and a method that takes values of this enum class as input, so I can enforce a constraint on the values I pass (vs. just passing a string). I mimicked the code here in the pybind tests.

If I expose my method with a standard def and the enum class this way:

py::enum_<Enum>(m, "Enum")
      .value("EntryOne", Enum::EntryOne)

m.def("method_using_enum", &addPenguinMetric, py::arg("enum_arg"), py::arg("other_arg"));

then invoke from python, with something like this (suppose my module/C++ file is called pyenum and other_arg is a string):

method_using_enum(Enum.EntryOne, "")

I run into an error since we can't seem to resolve Enum.EntryOne from Python to the original enum value Enum::EntryOne in C++. Does anyone have thoughts about whether this is something on my end, or is there no support for enum-typed arguments to functions exposed through pybind?
