Fixes for gcc 13, clang 16 and C++20

• Avoid use of deprecated is_pod
• Fix implicit capture of this (deprecated in C++20)
• Remove unused variables

Note that implicit capture of this via [=] causes a warning in C++20, but the new way [=,this] causes a warning in C++17, so we hide the C++17 warning (at some point we will stop supporting C++17).
