Programming puzzles: processing lists!

[pier4r]

Hold on. As far as my understanding of languages goes, I know that if you code in C, while the source is in C, the result is a binary for the CPU architecture (although with some overhead compared to the same binary produced from assembly code, this due to C being at a higher level than assembly).

Then there are the interpreters, like, say, python. Python should be a programming engine written in C that understand code and to avoid "understanding it again" can produce a sort of compiled version that is a bytecode.

So with a C binary the code should run without layers, directly CPU code.
With an interpreted language, there would be a first step to convert the program in internal code and then run the internal code using calls that run CPU code.

So, userRPL -> sysRPL -> saturn code (emulated) -> ARM code

while newRPL -> ARM code

python would be: python -> "compiled python" -> ARM code

When Claudio says "there is the inner layer of C code" it seems that the C code should be interpreted first, instead of being a binary.
Like: newRPL -> C -> ARM code

Am I mistaken?
