Wouldn't AST reflection be more complex to implement&use than a 
macro system? I mean, a macro system is quite functional in 
nature - the macro takes AST arguments and return an AST that the 
compiler embeds into the code. With AST reflection, you need to 
mutate an existing AST, which is more complex because order of 
execution matters.
