JS module API doesn't work within JavaScript

Running following code gives error "file.js:1: SyntaxError: Unexpected token .".

.import MyModule 1.0

console.log(MyModule.moduleAPI ? "MyModule is working" : "MyModule is not working")

Importing the same module inside namespace results in error "file.js:3: ReferenceError: Can't find variable: Module":

.import MyModule 1.0 as Module

console.log(Module.MyModule.moduleAPI ? "MyModule is working" : "MyModule is not working")

Same JS module API import, without initial dot ".", works within QML source file.

import QtQuick 2.0
import MyModule 1.0

Item { Component.onCompleted: console.log(MyModule.moduleAPI ? "MyModule is working" : "MyModule is not working") }

MyModule qmldir file contains "MyModule 1.0 MyModule.js". Attached example code as MyModule.tar.gz to reproduce the issue.
