I was just thinking about the case of processing a large file in chunks of an arbitrary size (where "lines" or "words" don't really work). I can think of a few approaches that would seem kind-of rakuish, but don't seem to be built-in anywhere... something like a variant of "slurp" with an argument to specify how much you want to slurp at a time, that'll move on to the next chunk the next time it's invoked...
Is there anything like that kicking around that I've missed?
