code: Node unsafeInline(Reference ref, String fnName, Node fnNode) {
      return internalInline(ref, fnName, fnNode);
    }
docs: Inline a function into the call site. Note that this unsafe version doesn't verify if the AST
  is normalized. You should use {@link inline} instead, unless you are 100% certain that the bit
  of code you're inlining is safe without being normalized first.
