I think it's a great idea because I did something similar with
Fortran-90. I have a programmable preprocessor that allows one to
write, in a C-like language, directives and transformations that
operate on programs. It's being used for parallelizing f90. You can
specify, for example, that a loop nest be dynamically distributed and
the preprocessor will examine the data structures used in the loops,
create temps, modify the loops, etc. So I guess I wouldn't call it a
macro language but it is a compile time language. It doesn't require
the user to understand all the gory details typically found in a
compiler, and, because one person can write directives, doesn't
require a formal standards process to add needed constructs.


There's more info at www.peakfive.com/p5_f90.html.
