Wolfram Alpha parses 1/2+2/3i as 1/2 + 2/(3i) and 1/2+(2/3)i as the
complex number with real part 1/2 and imaginary part 2/3.

That doesn't answer Todd's question. But this does:

If it weren't against math conventions, I wouldn't mind seeing 1-i1 or
1/2+i2/3. But I am sure the people who produce Racket or Scheme or Lisp readers
would hate me for that one, too. I think your students will need to cope, like
all people who study sophisticated concepts (such as complex).
