Traceback only show "File <string>" in case an error happen in the dictionary

This one isn't actually too difficult to implement, just use the importlib mechanism

		spec = importlib.util.spec_from_file_location(
				name=Path(filename).stem,
				location=filename)
		self.module = importlib.util.module_from_spec(spec)
		spec.loader.exec_module(self.module)
