This project is in an experimental stage. There are many holes in the implementation. Also, the C code generator has gotten a bit quirky and needs a refactoring pass. That said, RAI is being used for real work.
State threading for delay lines does not mix with the loop construct. Fixing this requires a better understanding of how to mix constants appearing on two levels: in type parameterizations and code.
Subsampling and block processing in the time dimension needs to be cleaned up and generalized.
