For interpretive infix use of '+' you could use WORD to get
the next number from the input stream and then use NUMBER to
push the number on the stack, then add them together using the
old version of '+'.
Since you can check whether you are compiling or not you can
make this safe, also you could make it use WORD to get the
next word then NUMBER and finally LITERAL to compile it in
RPN, afterwards use COMPILE + to put the old + in.
I don't think it is worth it, but it can be done.  I once
saw a Pascal compiler that was writeen in Forth (UGH).
