Problem description

在vs2019下编写回调函数接口引用pybind11/function.h时编译会显示“语法错误:意外的令牌标识符,预期的令牌为类型说明符”
头文件function.h的83行#if !(defined(_MSC_VER) && _MSC_VER == 1916 && defined(PYBIND11_CPP17))这个代码是否应该是
#if !(defined(_MSC_VER) && _MSC_VER >= 1916 && defined(PYBIND11_CPP17))

Research direction

Start with pybind11/function.h around line 83 and inspect how the _MSC_VER and PYBIND11_CPP17 condition affects callback interface compilation under VS2019. Reproduce the reported compiler diagnostic with a minimal callback interface, then verify that the header compiles successfully with the intended VS2019 versions.
