Left neuron reconnected to right neuron; took about a month. (Or is it one-and-half month?). Hope this won't be the cycle I'll get stuck in.
ML generation is probably a bad idea. Intermediate byte code is a good idea; reduced it to approx ten instructions. That should be enough.
Various edits (code.hi, lambda.hi, ml.hi, c.hi). Introduced lambda_expand. Re-evaluating thunk code, seems correct, but should be simplified.
