如何使用函数或变量重用模板文字？

Question

在初始表达/赋值之后，是否可以继续使用模板？

如预期的那样，它起作用：

const testTag = (strings, ...values) => console.log(strings, values);
testTag `${'this'}${'is'}${'test'}`;
> ["", "", "", ""], raw: ["", "", "", ""]
> ["this", "is", "test"]

这不是：

const testTag = (strings, ...values) => console.log(strings, values);
const testLiteral = `${'this'}${'is'}${'test'}`;
testTag testLiteral;
> Uncaught SyntaxError: Unexpected identifier

const testTag = (strings, ...values) => console.log(strings, values);
const testLiteral = `${'this'}${'is'}${'test'}`;
testTag `${testLiteral}`;
> ["", ""], raw: ["", ""]
> ["thisistest"]

const testTag = (strings, ...values) => console.log(strings, values);
const testLiteralMaker = () => `${'this'}${'is'}${'test'}`;
testTag `${testLiteralMaker()}`;
> ["", ""], raw: ["", ""]
> ["thisistest"]

const testTag = (strings, ...values) => console.log(strings, values);
const testLiteralMaker = () => `${'this'}${'is'}${'test'}`;
testTag(testLiteralMaker());
> thisistest
> []

const testTag = (strings, ...values) => console.log(strings, values);
const testLiteralMaker = () => `${'this'}${'is'}${'test'}`;
testTag(...testLiteralMaker());
> t
> ["h", "i", "s", "i", "s", "t", "e", "s", "t"]

((strings, ...values) => console.log(strings, values))(`${'this'}${'is'}${'test'}`)
> thisistest
> []

((strings, ...values) => console.log(strings, values))((() => `${'this'}${'is'}${'test'}`)())
> thisistest
> []

我对我可以使用模板文字编写可重用代码的方式很感兴趣，但是我无法理解两个函数如何有意义地共享它们。
