std::variant<< typo

[zwimer]

When generating bindings for a not-small project, Binder produced this output for me. As you notice, the variant's angle brackets are doubled up: std::variant<<bool ending with >>. You can see in the double-quoted bit of text below what the variant should be.

cl.def("index", (unsigned long (std::variant<<bool, std::string, float, double, std::shared_ptr<const PyObj::VS>, unsigned char, unsigned short, unsigned int, unsigned long long, BigInt, std::shared_ptr<const Expr::Base>, Mode::FP::Rounding, Mode::FP::Width>>::*)() const) &std::variant<bool, std::basic_string<char, std::char_traits<char>, std::allocator<char>>, float, double, std::shared_ptr<const PyObj::VS>, unsigned char, unsigned short, unsigned int, unsigned long long, BigInt, std::shared_ptr<const Expr::Base>, Mode::FP::Rounding, Mode::FP::Width>::index, "C++: std::variant<bool, std::basic_string<char, std::char_traits<char>, std::allocator<char>>, float, double, std::shared_ptr<const PyObj::VS>, unsigned char, unsigned short, unsigned int, unsigned long long, BigInt, std::shared_ptr<const Expr::Base>, Mode::FP::Rounding, Mode::FP::Width>::index() const --> unsigned long");

Thank you for letting me know @zwimer ! This looks like an issue with Binder indeed. Would you be open to create a minimal example (ie .hpp file with dummy declarations) that lead to this behavior so i can debug and fix this locally? Thanks,

I can provide the full sized example, but I don't currently have the bandwidth to narrow it down. I can also provide: MacOS 12, compiled binder with LLVM 11.0.0git; along with the config file I used and CLI arguments used to run binder.
