When specifying names for classes, functions, etc, are string literals required

E.g. py::class_ constructor

    class_(handle scope, const char *name, const Extra &...extra) {

adding a method

    template <typename Func, typename... Extra>
    class_ &def(const char *name_, Func &&f, const Extra &...extra) {

I'm not sure whether it would be ok to create a std::string on the fly and then pass in the c_str() pointer. The memory pointed to by the string would later become invalid -- is this ok? I.e., does pybind11 take a copy of the string passed in via the const char* parameters, or does it simply copy the pointer. It it copies just the pointer, I must ensure that memory to which the const char* points is immutable.

Hi,
this name in the end comes to the function
https://docs.python.org/3/c-api/unicode.html#c.PyUnicode_FromString
which creates a new reference,
so you may not be bothered about memory state imho

@evguran Many thanks, it's very kind of you to spend the time and answer this.
