Yes, that's troubling in a way, but if it is separated it is maybe alright. However, I have problems with systems that seem to say "here is nice high-level programming", but here's a way to subvert it. Layers and paradigms should be kept separate. If one paradigm is cross-bred with another, both paradigms lose their meaning and things begin to break down. > So does any language to somebody with a good debugger. Yes, there's no problem with knowing the lower level. On B5000 machines I knew the runtime well, could pretty much say what machine code any line of ALGOL would generate, could find my way around system dumps, far easier than on any other machine I have coded on. But did ALGOL ever need the programmer to subvert it at an assembler level? No. There WASN'T even an assembler. Thus the whole system was a self-contained package and you never needed to subvert the paradigm. Now that's a cohesive system. Seems when we need to dig around in internals the system is not actually cohesive. > Don’t think you’re safe if you program in C or C++. Never. C and C++ are the biggest reason for the sorry state of security we have on systems these days.
