I asked you to make an educated guess about what I would think of them,
which you didn't do. I wanted you to apply the Zen to macros so that
you could justify the guess. I wasn't interested in your thoughts.

What good are macros going to do when they entail (according to you)
saddling the language with all this unreadable crap? You may say
macros are not against the Zen of Python, but for their sake, you will
add a million things that are. Net effect is, you've taken away
everything that makes Python great.
But here's the best part: all of this is to avoid a "serious pain in
Get real, Paul.
Here's a thought: if macros are so great, it should be pretty easy for
you to create a halfway syntax with none of these pesky so-called
"arbitrary limitations" and have macros automatically turn it into
legal Python. Don't you think that's maybe better than turning the
language into an unreadable blob?
No, of course you don't, because an unreadable blob is the LISP way.

No, Paul, they're likely never to be related because Python is never
going to have macros. Or, at least not the general sort that you want.
