If you understood what MyHDL is doing, you'd know that doesn't matter.

Furthermore, most Python implementations are built using C, including the canonical one (CPython). It is possible to have performant Python implementations without using C, if that's what you're getting at.

No I am not simply talking about performance. I see you keep refering to Turing completeness in other replies, even condescendingly implying that your HN peers does not understand it, when you are clearly the one whose understanding needs to mature. A turing complete system is one where the rules are powerfull enough that you are able to implement "anything" INSIDE of them. Does'nt mean you are able to break out the system and manipulate the underlying environment, or even infer anything about how it's implemented. Just to bring my point to the extreme: Minecraft is turing complete. Does'nt mean you can bootstrap your cpu with. You can in theory emulate your cpu on top of it though.

Actually you seem to suggest that not even performance is of any hindrance to python. In which case I'm lost for words. You win.

I didn't think I'd have to spell things out so excessively, but... let's extend the description then... Any Turing complete language where you can write files to storage. To give an example of why the storage is relevant, let's look at Java. Java's sandboxed in the JVM right? However, if you think about it more broadly, as long as you can freely write files to disk you can write machine code to disk. In other words, as you can write a compiler in Java, you can break out of the sandbox.

As for Minecraft, I don't know enough about it, but if it's possible to write a compiler in Minecraft then that would have the same escape hatch too. It might not be a tool you choose to code a BIOS, but we're not looking at whether something is optimal, we're looking at whether something is possible.

Perhaps you overlooked the following quote as it didn't fit with what you decided you wanted to say...

"I didn't suggest Python is the optimal solution for low level coding, I just suggested it is an option."
