+      (Not, Seldom, Somewhat, Very, Extremely, Any). The Antecedent of a Rule
+      considers Any to be a syntactically special hedge because it is not
+      followed by a Term (e.g., `if Variable is any then...`). Amongst hedges,
+      only Any has virtual methods to be overriden due to its particular case.
