Artificial AST

Why not try it? Here's example implementation:
    
    
    import std/[macros]
    
    macro foo(): untyped =
      result = newStmtList(
        infix(
          newLit(1),
          "*",
          infix(
            newLit(2),
            "+",
            newLit(3)
          )
        )
      )
      echo result.repr # this line will print the code generated by a macro at 
compile time
    
    echo foo()
    
    
    Run

Here's the code generated by the macro:
    
    
    1 * (2 + 3)
    
    
    Run

Output is obviously - `5`

I hope this answers your question.
