    Nice! A few years ago I took a stab at this problem space with https://github.com/cesanta/v7 ; with fun tricks like in-place compacting GC, stdlib JS object graph "frozen" in rom etc

    Languages are not all equal nor do they all function in the same way, and that's not my opinion.

    Javascript syntax itself is one thing, and you can certainly feel free to Javascriptify some C++ libraries and make it all look a certain way for specific tasks, while managing things behind the scenes, up to a point... but there is no getting around the fact that SOMEONE and some languages are needed to implement low level systems functionality.

    the power of Cython or the Python C FFI is that it allows you to script/glue modular native code.

    You then state "C++14 may have been ratified 7 years ago but it's not the target code your build chain spits out"

    no, a C++ COMPILER spits out assembler code that then gets assembled and linked into an executable.

    The C++ or C code corresponds directly to a given set of assembler instructions which correspond directly to CPU instructions.

    You claim that Python programming of microcontrollers is mainstream, but this is not true nor possible. Python SCRIPTING of code modules (that cannot be written in Python) is certainly one way to assemble a system from pre-built legos.

    If you refer to knowing what I'm talking about as gatekeeping and egoism, might I suggest that you insist less forcefully in the correctness of incorrect things you state? we could be done with this spat in short order if YOU would refrain from speaking falsehoods. lies.untrue things.

    I look forward to your lisp c compiler. make sure that it's 100% lisp from the bottom up, or I'll consider you're having ceded my point. Consider that the lisp you author in has a garbage collection system that lisp cannot have written originally, nor has any semantics for the underlying memory structures of, but hey, I guess if one is committed to pretending that all languages are equal for all tasks, who am I to question ones self-identification with a given language.
