Well, yes and no.

There's a subset specification, and that turned into "EC++," which you can find here:

Since I retired from the computer industry, I haven't tracked the adoption/upkeep of the EC++ effort. Embedded SoC's grew up and removed some of the motivation for EC++, and yet other languages filled the void - one of these in embedded systems (esp. the Raspberry Pi project) was Python.

Today, when I'm hacking around on my own, the way I deal with C++ is that I simply don't. I just find another language to use, rather than deal with C++.
