More use cases please! (Unless you give up now. :-)

My major use case for (simple) macros would be AOP (aspect oriented programming), where calling a function can hurt you, especially for aspects like "do this on a development system, but not on the production system".

Currently, you need things like this:

if do_debug:
    some costly things

main code

if do_debug:
    collect info and write to log or something

So, instead of adding macros, might we think about a Pythonic (and efficient!) way to add aspects to the language?
