Since these are all "map functions" per bpftrace [1] and we're aiming to keep parity with that language, should we separate them from the vague list of "functions" into their own section? They can't be used elsewhere. -dv [1] https://github.com/iovisor/bpftrace/blob/master/docs/reference_guide.md#map-functions
