No its not like those 'compilers' i dont really agree with a compiler generating C/C++ and saying its producing native code. I dont really believe its truely within the statement. Compilers that do that tend to put in alot of type saftey code and debugging internals at a high level to get things working in other projects i am not saying python compilers here i havent analysed enough to say this.

What i mean as a front-end is jut like GCC G++ gccgo gfortran it all works the same each of these are front-ends you can pass all those mental gcc options like -O3 -mtune -fblabla. it is implemented as part of gcc and you can 'bootstrap python'. You can -fdump-tree-all etc.

What i can say is jit compilation is really mistified' in a big way when it comes to projects like pypy when its implemented in python how can it call mmap to make an executable memory block etc. When it comes to compilation i think it gets fairly mistified in the python compiler community even more.
