Right now, the deprecation function (for giving deprecation warnings) has an option to say when the deprecation took effect. Because of the way release numbers are decided, and because patches can be delayed getting in, saying when a deprecation took place is very hard, if not practically

For really fast generics I think you may need some kind of jit. Are generics handled by cython code or python code in sage? Does it cache anything? I recently encountered similar problems anyhow. A generic rref took 20 minutes to reduce a tiny (by my standards) matrix as part of a factoring

Just to be clear, I'm specifically talking about arithmetic by the way. Anything for which the python overhead is completely irrelevant, should of course be implemented in python. Arithmetic really screws up almost every aspect of computing. There's a group of related full employment problems

a) why sage used g95 in the first place (yes I know it's smaller, but it's not standard at all imho) Agreed. I can't see the point of it. Apparently because there was no gfortran for certain platforms. Now we assume Linuces (?) have this, but as Dima demonstrates, with OS X 10.4, somehow
