 inifile.aug:44 :

 inifile.aug:30 :

 It seems that `kw /[a-z][a-z0-9_-]+/` conflicts with `label "comment"`. I
 don't see any other explanation. If I change `label "comment"` to `label
 "Comment"`, the lens compiles properly, so it seems that the lens checker
 uses the labels to check for conflicts, which is a bug.
