one of my development goals is to move away from the limbo runtime and replace it with a new engine based on a combination of scheme and forth. this is very much inspired by prescheme and nanopass compiler development. learning about APL and BQN (especially co-dfns) has thrown me through a loop, so i might be revisiting some of this because data parallelism is something that i would love to have access to for scientific programming stuff that i want to do in the future.
