[REBOL] Re: From word to none

Arnaud had the same problem in his thread "sorting a serie ...."
Jan's serialised form of none solution suprised me as I still haven't got
used to that. But it a good way for future releases.
An "old way" would be to use reduce on your block.

Subject: [REBOL] From word to none
Hi
I have a hash of values in a file, and in this hash, some values are none!
The file looks like this:
make hash! ["some string" none none "some string" 55 438 {"29621"} ]
I go through the hash with foreach, like this:
foreach [a b c] hash [
if none? b [ print "We've got a none! value" ]
]
Now here's my problem: 'foreach gives the none values as word! values. How
can I get them as "real" none! values?
Thanks for any help,
~H
