[REBOL] Re: [ feature request /intelligence ]

I agree with you. If Rebol would automatically initialize words, I
cannot be advised if I made a typing error. Furthermore, I tested
another good language: Python... it behaves the same way: try this in
Python:
a=b+1
you will obtain this:
Traceback (most recent call last):
File "<interactive input>", line 1, in ?
NameError: name 'b' is not defined
