C++ allows declaring functions as constexpr. Such functions could be evaluated at compile time and used, for example in if constexpr(...). However, a non-constexpr function in this context is not allowed.
So, if we want to write a template, accepting a function and using it in either if constexpr(...) or old plain if(...) we need to test whether the function is constexpr, otherwise compile fails as illustrated below:

This post suggests an implementation of template class setof which facilitates features of a bit set and a forward-iterable container.
C++ does not allow using string literals as case values in a switch statement. In modern C++ this restriction can be worked around with constexpr hash values.

This simple C++17 template implements constexpr any_of for matching a value against a list of constants.

COJSON library is also available as Arduino Studio .ZIP library: cojson.zip.
(Continued)C++17 has simplified use of template parameters. Instructions, given in this tutorial, describes how to define
JSON model with cojson::autos templates.
Note: GCC 7 or higher is required to compile cojson_autos.hpp !
cojson v.2 offers an easy start option by using C++ code automatically generated from a JSON sample the user needs to parse or to write.
To use this option just open codegen page, load or copy-&-paste your JSON and copy-&-paste or save the generated C++ code.
And then build your application with cojson sources .
PSoC — Programmable System on Chip - is an ARM Cortex based family of MCUs (wiki) by Cypress Semiconductor. Cypress offers developers a dedicated IDE - PSoC Creator. Unfortunately, PSoC Creator, (as of version 4.2) does not support C++, despite the underlying GGC Toolchain (arm-none-eabi-gcc-5.4) has C++ support at descent level.
PSoC Creator has an option for migrating to Eclipse CDT IDE, however, migrated projects has no C++ support either
This post explains how to enable C++ for PSoC projects, imported in Eclipse CDT IDE.
