13 # inlined in the actual methods--but in my (LukeShu's) opinion, that
14 # makes the AWK code too difficult to edit; so they're split out to
15 # here. But splitting them out further and moving them out of the AWK
16 # would be too much--it'd create more things to keep in-sync and
17 # smearing the implementation across multiple files would make things
18 # harder, not easier.
