I think you need to specify what you mean by "without a runtime". Do you mean "without a garbage collector"? "Without memory allocation"? Even C has a runtime, just a very small one.
Can I do the same in rust?
Lies are flying all over.
I'll need to check that by myself one day.
What's seems to be really sure though is the filth of rust syntax complexity on par with the other filthy one, c++.
