[REBOL] Re: dictionaries

Hi Cavva,
As Sunanda pointed out, we use objects all the time
for this. eg:
make object! [print: "lost!"]
It looks in the above example that we have redefined the
word 'print. We have, but only the 'print in that object.
The value of 'print in the default, global context is still
the same and so 'print evaluates as usual.
In the following example I am binding a block of words
to a particular context. Those words which are found in
the context will be bound to the context. The rest of the
not-found words will keep their current binding:
a: "global"
b: "global"
ctx: context [b: "local"]
print bind [a b] ctx
;---> global local
You can bind huge chunks of code if you like.
This gives the same result as above:
do bind [print [a b]] ctx
;---> global local
Also if you want to get just one word out of a particular
object, you can use IN and GET:
print get 'a ;---> global
print get in ctx 'b ;---> local
