I have one thing to mention about something you wrote. You wrote, “it would be nice if Dojo could provide a way to “mix” a package into the global or local scope.” JavaScript itself allows for this. For example, if I have:

my.really.long.package.namespace.exampleObject.method1();
my.really.long.package.namespace.exampleObject.method2();

I can do this instead:

var exampleObject = my.really.long.package.namespace.exampleObject;
exampleObject.method1();
exampelObject.method2();
