Hrm. Here's the usual whiner. Feel free to ignore me if I get onto
your nerves [1] ;-)

That means that macros aren't anymore `first class objects'? What
consequences does this have for meta-programming?

[1] No, I do acknowledge that *you* are doing the work and I'm just
    sitting back and complaining. I wouldn't take any offense if
    you prefer to do more real work instead of taking the time to
    answer to my ramblings.
