Method declarations following this directive get the specified group identifier, which gives a better overview of the class through the manual tools (ClassBrowser).

The value @default (pushed by pce_begin_class/[2,3]) assigns a method to the same group as an inherited method of the same name, or the group miscellaneous if no such method exists. The directive has no semantic implications.

See also pce_begin_class/[2,3], pce_extend_class/1 and method<-group.
