在Scala中嵌入XML(和其他语言？)

所以我可以写：

val xml = {
  <myxml>
    Some wired text withoud "'s or code like
    import x
    x.func()
    It's like a normal sting in triple-quotes.
  </myxml>
}

xml.text

String = 
 "
    Some text wired withoud "'s or code like
    import x
    x.func()
    It's like a normal sting in triple-quotes.
  "

看源代码并没有给我洞察,怎么实现.
“XML检测”是(硬)Scala语言功能还是内部DSL？因为我想建立自己的这样的东西：

var x = LatexCode {
  sqrt{frac{a}{b}}
}

x.toString

"sqrt{frac{a}{b}}"

要么

var y = PythonCode {
  >>> import something
  >>> something.func()
}

y.toString
"""import something ..."""

y.execute  // e.g. passed to python as python-script

要么

object o extends PythonCode {
  import x
  x.y()
}

o.toString

"""import x...."""

我想避免使用像PythonCode {“”“import …”“”}之类的东西作为“DSL”.而在scala中,XML被神奇地传输到一个scala.xml-Class;与我可以用val a =’symoblname得到的符号相同,但是在源代码中没有线索如何实现.

我该怎么做,就像内部的DSL呢？
