I originally tried to add more template specializations to cover the "no parameters" variants, but that resulted in errors, since void func(void) was matching 3 different specializations:

external/proxy_wasm_cpp_host/src/v8/v8.cc:609:10: error: function template specialization 'getModuleFunctionImpl' ambiguously refers to more than one function template; explicitly specify template arguments to identify a particular function template
void V8::getModuleFunctionImpl(std::string_view function_name,
         ^
external/proxy_wasm_cpp_host/src/v8/v8.cc:115:8: note: function template 'proxy_wasm::(anonymous namespace)::V8::getModuleFunctionImpl<void>' matches specialization [with R = void, Args = <>]
  void getModuleFunctionImpl(std::string_view function_name,
