Dictionaries and Modules?

Having programmed for years in scripting languages (Python, Perl, Bash, et. al.), I really miss some features in ai2, most notablyDictionaries (Associative Arrays) and Modules (Libraries).
Are there plans to add these features in future App Inventor's versions?



Maybe, possibly sometime way down the line, but I doubt you'll see it any time soon.

Thanks Enis.
BTW, are there any URLs I can pursue that will help me implement my own extensions to ai2?
