Sure, but only details. We got most things right.

But let's assume we got it wrong and there is a superior IR that 
also the macro system should have access to. Then we would need a 
translation layer from the old AST to the new IR and back so that 
older code keeps working. But that's well trotted ground, see 
GCC's various different IRs (GENERIC, GIMPLE and RTL).
