@willco There's an easy, 2- or 3- line change that could be implemented that makes C++ very easy to set up. It can be implemented directly in the linker script and main file that ship with the SDK. It shouldn't take more than a quick glance from an engineer to verify that it works and is okay to include in the next SDK. It would make sharing C++ code between playdate developers much easier, as then we don't need to implement those changes in the SDK ourselves. I would really appreciate it if someone from Panic were to take a look at it. 
Edit: okay it's more like 30 lines but it's just in 2 places so it's not so bad.
