Real modules

[KCreate]

Modules should, instead of sharing a common global scope, be able to define what values they export via the injected variable export. The contents of this variable will be the result of the load or require call.

Example:

awesome-library/main.charly

class MyAwesomeClass {
    # code
};

export = MyAwesomeClass;

# More code follows

main.charly

let myClass = require("awesome-library");
print(myClass); # MyAwesomeClass
