[MLton-devel] request for better implementation of IO.Io

[Norman Ramsey]

My students are understandably confused to receive an error message
such as the following:

  ice3 ~ >> usmalltalk
  -> (use xxx)
  I/O error: <unimplemented>
  ice3 ~ >> 

I believe I've traced the problem to your implementation of the Io exception:

    ice3 ~ >> grep -w Io ~/src/instructor/usmalltalk/usm.sml
       | IO.Io {name, ...} => continue ("I/O error: " ^ name)
    ice3 ~ >> 

It would be nice if the value in the `name' field of the record could
be improved.
