Thanks. I got it working. I copied much of the code in client.jl. In the end I wrote the new mode directly into a copy of REPL.setup_interface. There is probably an easier way to get the REPL to start in the new mode rather than julia, but this was faster for me. There were many details, eg to get warn and error colors working. For me, it would have been far easier to use a hook after the REPL is created, but before it runs. But, I guess there is probably not much demand for that.
I also copied four functions, changing only `Base.parse_input_line(line)' in each (to support dumb terminals, etc.), to include a macro to post-process the AST. Again, I don't know if there is any demand for adding a general facility for this.
