[REBOL] Re: x: :y question

Ahoj Bolku,
<<Bolek>>
I had an idea: I need to sroll some face up or down, left or right
depending on some value.
I can use something like:
either x < 0 [a: a + 1][a: a - 1]
so I thought I can make it more REBOLish ;), something like:
op: either x < 0 [:+][:-]
a: a op 1
This does not work, OK.
<</Bolek>>
Prefix versions work OK, see this:
a: do either x < 0 [:add] [:subtract] a 1
<<Bolek>>
But Joel, what does mean your:
>> (+ 1 2)
== 3
?
I can't reproduce it, for me, it's always
>> (+ 1 2)
>>
(nothing happens, because type? (+ 1 2) is op!)
<</Bolek>>
This is probably a bug in the latest beta, before the operators worked as
prefix.
