Yes, it works, but the problem is neither camlp4 nor sed, but the pipe:
       sed ... | camlp4o foo.ml
       camlp4o ... | sed foo.ml

In these commands, the input file is not applied to the first command,
the pipe is unuseful. And I am not sure that it is a good idea to ask
ocaml to look at the string parameter. What it does is:
       Sys.command (the_pp_string_parameter ^ " " ^ the_input_file)

If you need sed just to define constants, it is possible with camlp4
alone. Well, I can add a system of macros like #define of C. Like that,
you would not need to program it, but just adding the good predefined
camlp4 cmo file. I am going to think of it.
