> We can use {{AstStringCompiler}} to construct AST in Java code, it will be especially useful when we want to implement {{ASTTransformation}} and generate complicated bytecode. For example,
> {code:java}
> AsmClassGenerator acg = controller.getAcg();
> // Using text block in Java 13(preview)
> new AstStringCompiler().compile("""
>      if ('a' == x) {
>           ...
>      } else {
>           ...
>      }
> """, CompilePhase.CONVERSION, true).get(0).visit(acg);
> {code}
> So we do not have to contruct AST with util methods of {{GeneralUtils}}  any more.
