Right, I was probably unclear.  One of the applications I am using
Scheme for is embedding experimental languages in it.  Some of them
process "programs" during evaluation time and should expand macros
by themselves.  In simple cases I use syntax-rules, in more complicated
I write low-level macros by hand -- in practical tasks like that they
are much simpler than syntax-case (and much smaller).
