Now now, jake,
Good C style code, can be made a lot more efficient, using the more expressive C++ compilers, as an assembler man, I present you proof https://godbolt.org/g/uq6p8o
If you've not had a play recently you might be surprised.
Now if you were to complain about bootstrapping a minimal C++ runtime, compared to a minimal C runtime, fair point, but the language is a fine one, in capable hands.
How's the greenhouse doing? I'd like my own slack powered farm one day, you make it sound a lot of fun.
