Is the reference to A required to get the implicit import and hence implicit
initialization? For example in:
module Outer {
/* no export */ module A {
console.log("you need me");
export var x = "x";
}
export function f() {
console.log("no reference to A");
}
}
I would expect inner modules to always be initialized when their outer module
is initialized
