[Cython] Funny idea: interpreted def functions
Hi, Pure Python functions rarely benefit from compilation. I thought it would be interesting to add an "interpreted" directive (global, module, class, function level + automatic heuristic) that will instruct Cython to compile def functions into _bytecode_ and store that bytecode in the binary. Together with module bundling and embed/freeze it could make a neat deployment solution. (I have no plans to implement this.)

Well, it shouldn't be all that hard to implement. Basically, we'd send a part of the source file through the Python parser after having parsed and processed it in the compiler. However, I fail to see the advantage of this feature that would make it worth providing to users. There usually *is* a visible performance advantage of compiled code over pure Python code, and the advantages of interpreted Python code in terms of semantics or compatibility are quite limited (debugging, maybe, or introspection). Could you describe how/why you came up with this? > (I have no plans to implement this.) I can imagine.

There usually *is* a visible performance advantage of compiled code over pure Python code, and the advantages of interpreted Python code in terms of semantics or compatibility are quite limited (debugging, maybe, or introspection). Let's just say there are legitimate reasons to stay interpreted, binary size and compatibility among them. Could you describe how/why you came up with this? Well, I was wondering why isn't CPython written in Cython (actually I know why) and how awesome it would be to have a system with CPython runtime and unified Cython/Python compiler front-end targeting both bytecode and native code. In such system, per-function compiled/interpreted switch would feel natural to me... That's how, if it answers your question. And from a different angle: many people praise Go(lang) for it's "single fat binary" deployment approach. First class bytecode support in Cython colud provide the same for Python. (Maybe not quite the same, but a step in this direction.) Best regards, Nikita Nemkin ___ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
