Ah, scrap that.

I was able to make the example work in the interactive prompt. But I am
still not able to make it run with running

poly --use my_file.sml

Is there any reason this should not work? Is there a difference in how code
is executed when it is "used" instead of typed by hand into the interpreter?

I would like to be able to script the debugging, and it would be very
helpful to be able to run it fully automated from the command line without
emulating input.

Regards, Morten
