I wonder if you can make this map global and use that map's keys() instead of
global_stat_names in _parse_global_stats() above. This way there'll be a single
point where you'll need to add a new global stat in this file.

[Dai Mikurube (NOT FULLTIME), 2013/03/14 11:26:22]

Yeah, I actually would like to do it, but it actually depends on the order of
global_stat_names.

I think about fixing the dependency, but it would be done in another change
since it needs more change.
