Roles of Variables in the Hedy programming language
summary
Applies the 11 Roles of Variables to Hedy and reduces them to 7 roles retained (splitting fixed into constant and input, merging organizer/container into list and dropping follower/temp), claims the original 11 cover 99% of novice variables, and maps where roles appear across Hedy’s 18 levels. Builds a prototype that annotates the editor’s variable view so prototype shows role in variable view and notes gatherer and flag are not yet implemented and no user study exists yet; Hedy is available in 54 languages.
