Maybe I'm missing the point of the question, but can't you just do it
exactly the same way?
Reader reader = new FileReader("clj/demo.clj");
Compiler.load(reader);
Var var = RT.var("demo", "even_sillier_adder");
Object result = var.invoke(4);
System.out.println("Result: " + result);
System.out.println("Result evaluated: " + Compiler.eval(result));
Output:
Result: (foo/silly_adder 9)
Result evaluated: 9
A macro is just a function that takes some code and returns some other
code, so "invoking" a macro will return the code it evaluates to. If
you want that to be then evaluated, then just ask the compiler to
evaluate it. ;-)
