It's only a macro system when you generate code in unexpected/unobvious places with it. This is more like inspect.getsource(), but going straight to the AST.
Is it really that much different? The end result is the same -- the user writes something that looks like a Python expression, but it gets evaluated using some other set of semantics that can be arbitrarily different from Python's.
I think the key difference is that the AST is not going to be converted to run different Python code under Python, but under some other language -- presumably to implement the semantics of the Python snippet. -- ~Ethan~
