You _always_ use macros for compile-time processing of code.

Gee, that explains the runtime errors I get when I try to call macros
then. <sigh>

I think this may be a non-native speaker thing. "use-for" does not mean
what you think it means ("use-at"). I use macros for (to achieve) new
syntax and to hide implementation.

Maybe. What I was trying to get at was that macros work at compile time
and the CLOS MOP can be more convenient when meta-level stuff is
required at run time.

FWIW, that was clear to this particular native speaker of English.
I think it would be clear to most.
