[REBOL] Understanding +
From: apwing:zonnet:nl at: 16-Dec-2003 11:02
Hello list,
there is a difference between the documentation of the + function in the REBOL dictionary
and the one I get with HELP +.
In the first one usage says that + a b should work, while the last one says usage should
be a + b.
Now when I try it at the console I get for:
>> 1 + 2
== 3
>>
and for:
>> + 1 2
>>
so in the last case no value seems to be returned. Which makes me think that the USAGE
direction of the Dictionary is bad. (Is that correct?)
When i do:
>> print [ + 1 2 ]
?op?
>>
the value "?op?" is returned.
And when I do:
>>reduce [ + 1 2 ]
== [op]
>>
something similar is returned.
Obviously these values are related to + being an OP! value as in:
>> op? :+
== true
but still it is not totally clear to me why the word "op" or even "?op?" is being returned
instead of "op!" in the 2 last cases.
Perhaps one of you can explain this to me?
Thanx so far!
Met vriendelijke groet / with kind regards,
Arie van Wingerden

REBOL: XML can't parse itself.
