[REBOL] Re: Don't understand "try" and "disarm"

I don't think they are needed by any stretch, they just make things easier.
I don't think REBOL needs a keyword! datatype. I think think syntax to do:
>> foo: 'foo
would be handy. In Lisp, this is the ':' token, but in REBOL this is used as
[almost] a synonym for get. Using some other token might make things easier.
Just a method of auto-interning a new symbol that is automatically set to
point to itself when evaluated.
