Can't pass vectors arguments such as std::vector<std::string> to commands in v2.0

/xxxxx/cli/include/cli/detail/fromstring.h:268:23: error: no match for ‘operator>>’ (operand types are ‘std::stringstream {aka std::__cxx11::basic_stringstream<char>}’ and ‘std::vector<std::__cxx11::basic_string<char>, std::allocator<std::__cxx11::basic_string<char> > >’)

Can you please provide also the code that generates the compilation error?
Thank you.

A simple modification to the example simplelocalsession.cpp can reproduce this problem:

    rootMenu -> Insert(
            "answer",
            [](std::ostream& out, int x, std::vector<std::string> strs){ out << "The answer is: " << x << "\n"; },
            "Print the answer to Life, the Universe and Everything " );

Unfortunately mixing std::vector<std::string> with other parameter types is not currently supported.

As a workaround, you can use the first parameter of the vector as an int, by converting it from string in your code.

However, if you think this can be a useful feature, you can open an issue with a feature request (maybe you can also consider sponsoring the project using the heart icon on top of the page to speed up this development).
