Extra explanation for this one. There's an issue in how the interpreter sees op! values (anything with infix notation), so the infix use of the op is lost here. That's why it's prefix notation inside the print block. --=20 =E5=A5=8F=E3=81=A7=E3=81=A6=E5=A4=A2 -- To unsubscribe from the list, just send an email to lists at rebol.com with unsubscribe as the subject.
