> The use of Python’s context managers considerably reduces the size of the generated parsers for code clarity, and enhanced CPU-cache hits. I would love to hear more about how it affects cache hits.

It's just stack based memory that automatically cleans up. Given their storage on the stack (rather than heap), they have better cache properties. https://docs.python.org/3/library/contextlib.html https://docs.python.org/3/library/contextlib.html

  I couldn't find in the link any mention of heap or stack-based storage. Where can I find more info about it?

  Eh python’s stack variables are on the C heap, so I don't think that interpretation makes any sense.
