[REBOL] Re: facts we will have to face ...

I don't know about the Python situation but Squeak [1] handles the situation in a couple of ways. One is to write the code in 'C' and load it as a dynamic library or link it in. If the extension is popular enough people port that 'C' library to the other platforms. Another approach taken is to write the extension in a cut down Smalltalk dialect which Squeak can compile to 'C' code and is then linked in. This becomes more portable across the platforms but still requires a bit of tweaking across platforms. This is how the 3D engines became optimised. They started in smalltalk and then various parts of it were written as 'plug-ins' to get more speed. The MP3 and MPG support started with using an open source library that did all the work and passed the image/sound data to Squeak which then blasted it to the screen or sound system. Worked quite well. Since REBOL has the ability to load dynamic libraries and call C functions (Pro only?) then similar could be done there. [1] Chris.
