Another thing I'm considering--though I could be wrong about this--is sage.ext.fast_callable. I only even found out about this by working on fixing sage.ext.interpreters to build in Cygwin. (I've heard mention of fast_callable before but nobody explained very well what it is--the documentation is fine though). I wish I had know about this sooner, and furthermore I wish it had been usable and discoverable outside of sage. I've done a lot of the same work myself, and have merely protyped some of the kind of bytecode generation from expressions that it does--never had the time to get that fully working though. Currently sage.ext.fast_callable is written in such a way that depends on some of sage's core data structures, but I'm not convinced it needs to be that way. With some reworking and more extensibility I think it could be redesigned in such a way that doesn't depend on sage, but that sage can easily build on top of to add specific support for its structures. A good example where this is already done is in how ElementInterpreter extends PythonInterpreter to check that sage Elements are in the correct parent domain (IIUC).
