[BUG]: Cannot parse Enum in unnamed namespace

[sogoogos]

Problem description

I have something like:

#include <iostream>

namespace
{
    enum MyEnum
    {
        A,B
    };
}

int main(){
        std::cout << "hello" << std::endl;
}

Then got:

In [8]: header = CppHeaderParser.CppHeader("main.cpp")
---------------------------------------------------------------------------
CppParseError                             Traceback (most recent call last)

   2976 if self.stack and self.stack[0] == "class":

   3426 debug_print("trace")

   3428 self.stack = []

File ~/.edm/envs/pmapp/lib/python3.8/site-packages/CppHeaderParser/CppHeaderParser.py:3593, in CppHeader._parse_enum(self)
   3592 if tok.value != "enum":
-> 3593     raise self._parse_error((tok,), "enum")
   3595 location = tok.location

CppParseError: unexpected 'namespace', expected 'enum'

The above exception was the direct cause of the following exception:

   3120 self.finalize()
   3121 global parseHistory

cxxheaderparser can handle that (see https://robotpy.github.io/cxxheaderparser/ for a live demo you can paste that into).

I'm happy to accept PRs to fix this, however.

I was not aware of cxxheaderparser repo. I would switch to it once pip distribution becomes available

I wish I could but unfortunately, I do not have currently the bandwidth for it.
